Whether your child is a young minor living abroad or an adult son or daughter you have not been able to reunite with since immigrating to the United States, US immigration law provides a path to bring them here as lawful permanent residents. But the right path — and how long it takes — depends on two critical variables: your own immigration status (US citizen vs. green card holder) and your child’s age and marital status at the time you file and at the time the visa becomes available.
The differences are significant. A minor, unmarried child of a US citizen is an immediate relative — the fastest category in family-based immigration, with no annual visa cap and no queue to wait in. The same child, if their parent holds only a green card, falls into a preference category and may wait years. An adult child — over 21 and unmarried — faces a waiting period even when their parent is a US citizen. And a married child of any age can only be sponsored by a US citizen, not a green card holder, and also faces a substantial wait.
Boston immigration attorney Giselle M. Rodriguez helps parents at every stage of this process — from filing the initial petition to preparing for the visa interview or green card application years later. This page explains the different pathways, what to expect, and how Giselle can help your family.
Which Category Applies to Your Child? A Quick Reference
The table below summarizes how your child is classified under US immigration law, depending on your status and their situation. Understanding your category is the essential starting point.
| Your Status | Child’s Situation | Category | Wait? |
| US Citizen | Unmarried, under 21 | Immediate Relative (IR-2) | No cap, no queue — fastest path |
| US Citizen | Unmarried, 21 or older | First Preference (F1) | Yes — capped, visa queue applies |
| US Citizen | Married, any age | Third Preference (F3) | Yes — capped, significant wait |
| Green Card Holder (LPR) | Unmarried, under 21 | Second Preference A (F2A) | Yes — capped, moderate wait |
| Green Card Holder (LPR) | Unmarried, 21 or older | Second Preference B (F2B) | Yes — capped, longer wait |
| Green Card Holder (LPR) | Married, any age | Not eligible | Cannot petition for married children |
Path 1: Immediate Relative — Minor, Unmarried Child of a US Citizen (IR-2)
| ✅ Fastest path in family immigration — no annual cap, no visa queue |
If you are a US citizen and your child is unmarried and under 21 years old, they qualify as an immediate relative under US immigration law. This is the most favorable category in the entire family-based system. Unlike every other category discussed on this page, there is no annual cap on immediate relative visas and no priority date queue to wait in. Once the I-130 petition is approved, your child can proceed directly to their immigrant visa or green card application.
Key Facts
- Your child must remain unmarried. Marriage at any point before they receive their green card converts their classification and removes them from the immediate relative category.
- Age 21 is the bright line. If your child turns 21 before the green card is issued, they lose immediate relative status. This is called “aging out.” The Child Status Protection Act (CSPA) may protect your child from aging out in some circumstances by adjusting how their age is calculated. See below.
- Two pathways to the green card. If your child is already in the US on a valid temporary visa, they may be eligible for adjustment of status (Form I-485), avoiding the need to travel abroad. If your child is outside the US, the case proceeds through consular processing at the US Embassy in their country.
- Typical timeline. From I-130 filing to green card, the process typically takes 12 to 24 months — sometimes less. The main delays are USCIS processing time (currently 12–18 months for I-130 petitions for immediate relatives), then a few months for NVC processing and the consular interview or USCIS adjustment of status interview.
- Children of US citizens cannot be included as derivatives. Unlike in some preference categories, children cannot simply be “added” to a parent’s immediate relative petition. Each child requires a separate Form I-130.
Path 2: Unmarried Adult Child of a US Citizen (F1)
| ⏳ Capped category — visa queue applies — wait of several years for most countries |
If you are a US citizen and your child is unmarried and 21 or older, they fall in the First Preference (F1) category. Congress allocates approximately 23,400 F1 immigrant visas per year, subject to per-country caps. Because demand regularly exceeds supply, there is a waiting period between when the petition is filed and when a visa becomes available.
Key Facts
- Your child must remain unmarried. If your adult child marries before their green card is issued, their classification automatically converts from F1 to the Third Preference (F3) category for married children of US citizens, which has its own separate — and also significant — waiting period. Marriage never accelerates the process; it often delays it.
- Current wait times (as of April 2026). For most countries, F1 Final Action Dates are currently around September 2017 — meaning petitions filed approximately 8–9 years ago are now becoming current. For countries with high demand (particularly Mexico and the Philippines), wait times are much longer. Wait times shift monthly with the Visa Bulletin.
- File as early as possible. The priority date — your child’s place in line — is set the day USCIS receives the I-130 petition. Every month you delay filing means a later priority date and a correspondingly later visa.
- The F2B-to-F1 upgrade: a special case for LPR parents who naturalize. If you filed an F2B petition for your adult unmarried child when you were a green card holder and you subsequently naturalize, the petition automatically converts to F1 and your child retains their original priority date. In some situations, the F2B queue moves faster than F1, so the Child Status Protection Act allows your child to opt out of the conversion and remain in F2B. Please note, if any changes occur, please ensure that USCIS or the NVC is notified so they can update their records accordingly. A consultation with an attorney is worthwhile when naturalization is approaching.
Path 3: Married Child of a US Citizen (F3)
| ⏳ Capped category — substantial wait — spouse and minor children may immigrate as derivatives |
If you are a US citizen and your child is married (regardless of their age), they fall in the Third Preference (F3) category. Congress allocates approximately 23,400 F3 visas per year, again subject to per-country caps. Green card holders cannot petition for married children at all — this pathway is available only to US citizens.
Key Facts
- Spouse and minor children can be included. The married child’s spouse and any unmarried children under 21 may immigrate as derivative beneficiaries on the same petition, without requiring separate I-130 filings for each of them.
- Current wait times (as of April 2026). For most countries, F3 Final Action Dates are currently around July 2012 — a wait of approximately 14 years from filing. Mexico and the Philippines have significantly longer backlogs. Like all preference categories, dates are updated monthly in the Visa Bulletin.
- Divorce can improve the category. If an F3 beneficiary divorces before their visa is issued, their petition may automatically convert back to the F1 category (if they are 21 or older) — which, depending on current Visa Bulletin dates, may represent a shorter remaining wait. Conversion is not guaranteed to be faster; it depends on the dates in effect at the time. Please note, if any changes occur, please ensure that USCIS or the NVC is notified so they can update their records accordingly.
- Green card holders cannot petition for married children. This is a critical distinction. If you are a permanent resident and your child is married, there is no family-based petition you can file for them at this time. You would need to become a US citizen before you could petition for a married child.
Path 4: Minor, Unmarried Child of a Green Card Holder (F2A)
| ⏳ Capped category — wait required — but one of the faster preference categories |
If you are a lawful permanent resident (green card holder) and your child is unmarried and under 21, they fall in the Second Preference A (F2A) category. This is the most favorable preference category for LPR parents. Congress allocates approximately 87,934 F2A visas per year, and importantly, 75% of F2A numbers are exempt from per-country caps — meaning applicants from high-demand countries like Mexico, India, China, and the Philippines face a much shorter wait than in other preference categories.
Key Facts
- Current wait times (as of April 2026). The F2A category has been broadly current or near-current in recent years for most countries, though this fluctuates. Applicants should monitor the Visa Bulletin. When F2A is current, a child who is in the US on a valid visa may be able to file for adjustment of status without a significant wait after I-130 approval.
- Aging out is a real risk. Because processing times can take years (and the wait in the queue adds more), a child who is under 21 when the petition is filed could turn 21 before their visa is issued, moving them out of F2A (which then becomes an F2B case). The Child Status Protection Act (CSPA) may protect the child from aging out in some circumstances by freezing their “immigration age” using a formula that subtracts USCIS petition processing time from their true age on the date the visa became available.
- Naturalization of the parent converts the category. If you naturalize while an F2A petition for your child is pending and your child is still under 21 at the time you naturalize, their petition automatically upgrades to the immediate relative (IR-2) category — eliminating the wait and the visa cap entirely. This is one of the most powerful benefits of naturalization for parents of young children.
- Your child must remain unmarried. Marriage before the green card is issued terminates the F2A petition. Unlike US citizens, LPR parents have no pathway to petition for a married child.
Path 5: Unmarried Adult Child of a Green Card Holder (F2B)
| ⏳ Capped category — longer wait than F2A — naturalization can accelerate significantly |
If you are a lawful permanent resident and your child is unmarried and 21 or older, they fall in the Second Preference B (F2B) category. Congress allocates approximately 26,266 F2B visas per year (23% of the overall F2 allocation), which is considerably fewer than F2A. Waits are substantially longer than F2A.
Key Facts
- Current wait times (as of April 2026). For most countries, F2B Final Action Dates are currently around 2018–2019 — a wait of roughly 6–8 years. For Mexico, the wait is much longer. Dates move monthly.
- Your child must remain unmarried throughout. If your adult child marries at any point before the visa is issued, the petition is automatically revoked. No immigration pathway then exists for a married child of a green card holder through family-based immigration.
- Naturalization converts F2B to F1 — and may allow the priority date to be preserved. When an LPR parent naturalizes, a pending F2B petition converts to the F1 category. The child retains their original priority date. Depending on Visa Bulletin dates at the time, F1 may move faster or slower than F2B. The CSPA allows the child to opt out of the conversion and remain in F2B if that is more advantageous. Please note, if any changes occur, please ensure that USCIS or the NVC is notified so they can update their records accordingly. A consultation with an attorney before you naturalize is strongly recommended.
- Minor children of the F2B beneficiary may be derivative beneficiaries. If your adult child has their own children (unmarried and under 21), those grandchildren of yours may qualify as derivative beneficiaries on the F2B petition and can receive green cards alongside the principal beneficiary.
The Marriage Restriction: A Critical Point for All Categories
| ⚠️ Marriage Ends the Petition for Green Card Holders — and Changes the Category for US Citizens For lawful permanent residents: there is no family-based pathway for a married child. The F2A and F2B categories are open only to unmarried children. If your child marries before their green card is issued, the petition is revoked and generally no petition can be refiled under any LPR-based category. The only path forward is for you to naturalize and petition under the F3 category as a US citizen. For US citizens: marriage does not end the child’s eligibility, but it changes the category — from the immediate relative (if under 21) or F1 (if 21+) category to the F3 category for married children of US citizens. F3 has its own significant waiting period and per-country caps. Marriage before the green card is never an acceleration — it always slows things down. |
Aging Out and the Child Status Protection Act (CSPA)
One of the most emotionally difficult situations in child immigration is a child who was a minor when the petition was filed — but who turns 21 before the visa is issued due to processing backlogs. This is known as aging out, and it can result in a child losing a more favorable immigration classification after years of waiting.
Congress recognized this unfairness and enacted the Child Status Protection Act (CSPA) to protect certain children from aging out. CSPA does not change the legal definition of a child (unmarried and under 21). Instead, it provides a formula for calculating an “immigration age” that may be lower than the child’s actual age:
- For immediate relative petitions (minor children of US citizens): if the child turns 21 while the I-130 petition is pending, their age is “frozen” as of the date the petition was filed. They remain classified as a child as long as they are unmarried and the petition was filed before they turned 21.
- For preference category petitions (F2A for LPR parents): CSPA calculates the “CSPA age” by subtracting the number of days the I-130 petition was pending with USCIS from the child’s true age on the date the visa became available. If the CSPA age is under 21, the child may remain in the F2A category. The child must also seek to acquire the visa within one year of the date the visa became current.
- For F2A cases where the parent naturalizes: if an LPR parent filed F2A for a child who is under 21 at the time the parent naturalizes, the petition converts to immediate relative status and the child cannot age out of that status as long as they remain unmarried. Please note, if any changes occur, please ensure that USCIS or the NVC is notified so they can update their records accordingly.
CSPA calculations can be complex. If you have a child who is approaching 21 or has already turned 21 during a pending petition, a consultation with an immigration attorney is strongly recommended. See also: Child Status Protection Act.
Process of Helping Your Child Immigrate to the US: Step by Step
While the specific steps vary somewhat by category and whether the child is inside or outside the US, the general process for a child’s immigration petition follows this sequence:
| Step | Stage | What Happens |
| 1 | File Form I-130 with USCIS | The US citizen or LPR parent files Form I-130, Petition for Alien Relative, establishing the parent-child relationship. A separate I-130 is required for each child. Filing fee: $625 (online) or $675 (paper). The filing date becomes the child’s priority date for preference categories. |
| 2 | USCIS Approval | USCIS reviews the petition and supporting documents. USCIS may issue a Request for Evidence (RFE) if documentation is incomplete. Upon approval, USCIS notifies the petitioner. For immediate relatives, the case proceeds immediately. For preference categories, the case is sent to the National Visa Center and waits until the priority date is current. |
| 3 | Priority Date Becomes Current (Preference Categories Only) | For preference category cases (F1, F2A, F2B, F3), the child must wait until their priority date appears as current in the Visa Bulletin. For immediate relatives (minor children of US citizens), this step is skipped entirely. |
| 4 | NVC Processing | The National Visa Center sends instructions to submit the immigrant visa application (Form DS-260 for consular cases), pay fees, and submit civil documents (passport, birth certificate, police clearances, etc.). The petitioner files the Affidavit of Support (Form I-864). |
| 5 | Medical Examination | The child undergoes a medical exam with a US Embassy-approved panel physician in their home country (for consular processing cases). For adjustment of status cases inside the US, the medical exam is conducted by a USCIS-approved physician and filed concurrently with Form I-485. |
| 6 | Interview | For consular processing: the child attends an immigrant visa interview at the US Embassy or Consulate in their country. If approved, they receive an immigrant visa and become a permanent resident upon entering the US. For adjustment of status (child already in the US on valid status): the child attends an interview at the local USCIS field office in Boston. |
| 7 | Green Card Issued | Upon approval, the child receives a green card (Form I-551). Depending on the child’s age and how long they have been married to the petitioner (for derivative beneficiaries), the card may be valid for 2 years (conditional) or 10 years (permanent). A conditional card requires filing Form I-751 before expiration. |
The Naturalization Effect: Why Becoming a US Citizen Can Transform Your Child’s Case
One of the most powerful levers available to a parent who is a lawful permanent resident is naturalization. Becoming a US citizen can dramatically change — and often dramatically accelerate — a pending child petition:
- F2A (minor child of LPR) → Immediate Relative: if you naturalize while an F2A petition is pending and your child is still under 21 when you naturalize, their petition converts to the immediate relative category. The visa cap disappears. The queue disappears. Your child’s case moves to the front of the line.
- F2B (adult unmarried child of LPR) → F1: if you naturalize, the F2B petition converts to F1. Your child retains their original priority date. Whether F1 is faster or slower than F2B at the time depends on current Visa Bulletin dates — but the option to opt out and remain in F2B is available under the CSPA if F2B is more favorable.
- New ability to petition for married children (F3): once you become a US citizen, you can petition for a married child under the F3 category — a pathway that does not exist at all for green card holders.
For any LPR parent who is considering naturalization, the impact on pending or future child petitions is an important factor to discuss with an immigration attorney before filing the N-400. Giselle can help you understand the implications and time the filing optimally.
Your Challenges as the Petitioning Parent
1. Documenting the Parent-Child Relationship
The legal definition of a qualifying “child” under US immigration law is specific. In addition to biological children, it includes stepchildren (if the marriage creating the step-relationship occurred before the child turned 18), legally adopted children (if the adoption occurred before the child turned 16 and the child has been in the legal custody of and has lived with the adopting parent for at least two years), and children born out of wedlock (with specific requirements depending on whether the petitioner is the father or mother). Documents must be consistent: inconsistent name spellings, translated documents not meeting USCIS standards, and missing adoption or legitimation records are among the most common triggers for a Request for Evidence (RFE).
2. Managing the Aging-Out Risk
For parents with children who are under 21 when the petition is filed — or close to 21 — the risk of aging out is real. USCIS processing times, NVC delays, and Visa Bulletin wait times can collectively push a child past their 21st birthday before the green card is issued. Understanding how the Child Status Protection Act applies to your specific situation — and acting within required timeframes — can preserve your child’s eligibility.
3. The Affidavit of Support
When the case reaches the NVC stage, you will be required to file Form I-864, Affidavit of Support, demonstrating that your income meets at least 125% of the federal poverty guidelines for your household size. This is a legally binding commitment that remains in effect until your child becomes a US citizen, earns 40 work quarters of Social Security credit, departs the US permanently, or dies. If your income falls short, a joint sponsor may co-sign.
4. Keeping Contact Information Current Over Years
For preference category cases with multi-year waits, the most mundane challenge can become a real problem: staying connected to a case that may be dormant for years. USCIS and the NVC communicate by mail. Missed notices due to changed addresses have derailed many long-pending petitions. Keeping your address current with USCIS and the NVC throughout the wait is essential.
5. The Marriage Question
For parents with adult children in the F1 or F2B queue, your child’s marriage during the wait is a life event that has major immigration consequences. Marriage converts an F1 case to F3 (if you are a US citizen) and terminates an F2B case entirely (if you are an LPR). Helping your child understand these stakes — especially as the priority date approaches and the wait is finally nearing its end — is important. An attorney can advise on strategy when marriage is being considered.

Frequently Asked Questions
My child is 18 and I just became a US citizen. How does this work?
An 18-year-old unmarried child of a US citizen is an immediate relative. File Form I-130 now. There is no visa cap, no queue, and the case should move forward to a green card within roughly 12–24 months. Because your child is still under 21 and unmarried, they qualify for the fastest pathway available in family immigration. Do not wait — their 21st birthday is the bright line.
My child just turned 23 and I’m a US citizen. They are not married. What category are they in?
An unmarried child who is 21 or older is in the First Preference (F1) category. File Form I-130 now to establish the priority date. The current wait for F1 (for most countries as of April 2026) is approximately 8–9 years. Your child must remain unmarried throughout the wait.
My child is 28 and married. I am a US citizen. Can I still petition for them?
Yes. A married child of a US citizen falls in the Third Preference (F3) category. Their spouse and any unmarried children under 21 can also receive green cards as derivative beneficiaries. The current F3 wait (for most countries as of April 2026) is approximately 14 years. File now to establish the priority date.
I have a green card, not citizenship. My child is 24 and unmarried. Can I petition for them?
Yes. Your adult unmarried child falls in the F2B category. File Form I-130 now. Current F2B wait times for most countries are roughly 6–8 years. If you naturalize while the petition is pending, the case converts to F1 and your child retains their original priority date. If F2B is moving faster than F1 at the time of your naturalization, your child may opt out of the conversion.
I have a green card and my child is 30 and married. Can I petition for them?
No. There is no family-based immigration category for the married child of a lawful permanent resident. If you want to petition for a married child, you must first become a US citizen. Once you naturalize, you can file an F3 petition for your married child.
My child was under 21 when I filed, but they are about to turn 21. What happens?
This is a critical juncture. The Child Status Protection Act (CSPA) may protect your child from losing their classification, depending on the category and the specific facts of your case. For immediate relatives (minor children of US citizens), if the petition was filed before the child turned 21, CSPA freezes their age for immigration purposes. For preference categories, the CSPA age formula subtracts the USCIS petition processing time from the child’s true age when the visa becomes available. Consult an immigration attorney as soon as this issue arises — the timeframes for action are strict.
My child is in the US on a student visa. Can they apply for a green card here?
If your child is in the US on a valid temporary visa and their priority date is current (or they qualify as an immediate relative), they may be eligible for adjustment of status — applying for the green card from inside the US without leaving the country. This is generally preferable to consular processing if available, as it avoids the risk of triggering any unlawful presence bars upon departure. Consult an attorney to evaluate eligibility.
Can my child become a US citizen automatically if I am a citizen?In some circumstances, yes. If your child is under 18, is a lawful permanent resident, and resides in the US in your legal and physical custody, they may automatically acquire US citizenship under the Child Citizenship Act of 2000 — without any naturalization application. Additionally, children born abroad to US citizen parents may already be US citizens by birth in some circumstances. Giselle can help evaluate whether your child qualifies.
