Can a U.S. Citizen Sponsor a Child Over 21? F1 vs F3 and Wait Times

Yes, a U.S. citizen can sponsor a child over 21 for a green card, but the petition goes into a capped family preference category with a long line. Depending on whether your son or daughter is married and where they were born, the wait for a visa number runs from roughly nine years to more than two decades. The petition itself is straightforward; the wait is the hard part.

F1 or F3: Which Category Your Child Falls Into

Immigration law splits adult children of U.S. citizens into two groups based on marital status. Unmarried sons and daughters age 21 or older fall into the first preference category (F1). Married sons and daughters of any age fall into the third preference category (F3).¹ Both are subject to annual numerical limits of roughly 23,400 visas each, with some spillover from unused visas in other preference groups.²

The distinction matters beyond the label. If an F1 beneficiary marries while waiting, the petition automatically converts to F3, which usually has a longer backlog. If an F3 beneficiary divorces or is widowed, the petition converts back to F1.³ A marriage or divorce during the wait can add years to the process or shave years off it.

How Long the Wait Actually Is

The State Department publishes a monthly Visa Bulletin showing which priority dates are currently being processed. As of mid-2025, F1 (unmarried adult children) is processing cases filed around July 2016 for most countries, roughly a nine-year backlog. F3 (married adult children) is processing cases from about August 2011, roughly 14 years.⁴

For beneficiaries born in Mexico or the Philippines, the waits are much longer. The July 2025 Visa Bulletin shows:

F1, Mexico: processing April 2005 cases — roughly 20 years
F1, Philippines: processing July 2012 cases — roughly 13 years
F3, Mexico: processing February 2001 cases — roughly 24 years
F3, Philippines: processing December 2003 cases — roughly 21 years

Filing early is what you can control. The petition won’t move faster once it’s in line, but the date you file locks in your child’s place. That filing date becomes the “priority date,” and it’s what determines when a visa number opens up.⁴

Over a wait this long, the petitioner sometimes dies before the case finishes. Federal law lets certain beneficiaries who were living in the United States at the time of the petitioner’s death continue pursuing the green card. Beneficiaries abroad have a harder path but can request humanitarian reinstatement.⁵

Filing the I-130 Petition

The process starts when you file Form I-130, Petition for Alien Relative, with USCIS. This form establishes the qualifying parent-child relationship and gets your son or daughter into the queue. You need to file a separate I-130 for each child you’re sponsoring, and you can file online or by mail.⁶

There is no minimum age to petition for your own son or daughter. The 21-year-old petitioner rule that applies when sponsoring parents or siblings does not apply here.⁶ You do need to be at least 18 and living in the United States to later sign the Affidavit of Support.⁷

You’ll submit with the I-130:

Proof of U.S. citizenship: a birth certificate, U.S. passport, naturalization certificate, or certificate of citizenship
Proof of the parent-child relationship, typically the child’s birth certificate showing you as a parent
Certified English translations of any document not originally in English

USCIS charges a filing fee that changes periodically, so check the current amount before you file.⁸

Proving You Can Support Your Child Financially

Before your child can receive an immigrant visa, you must file Form I-864, Affidavit of Support, showing you earn enough to keep the sponsored relative off means-tested public benefits. For most sponsors, the threshold is 125% of the Federal Poverty Guidelines for your household size.⁹

As of March 2026, the 125% thresholds for the 48 contiguous states are:

Household of 2: $24,650
Household of 3: $31,075
Household of 4: $37,500
Each additional person: add $6,425

Alaska and Hawaii use higher thresholds, and the numbers are updated annually. Confirm the current figures on the USCIS I-864P page before filing.¹⁰ Your household size includes yourself, your dependents, anyone you’ve previously sponsored who hasn’t naturalized, and the person you’re now sponsoring.

You’ll submit your most recent federal tax return, W-2s, and any 1099s. Pay stubs from the past six months or an employer letter can support the picture if the tax return alone doesn’t tell the whole story.⁹

If your income falls short, a joint sponsor can step in. A joint sponsor must be a U.S. citizen or lawful permanent resident, at least 18, and living in the United States, but does not have to be related to you or your child. Up to two joint sponsors can participate, and each must independently meet the income requirement for the people they’re sponsoring. Even with a joint sponsor, you as the petitioner must still file your own I-864.¹¹

Can Your Child’s Spouse and Kids Come Too?

Yes. Your adult child’s spouse and unmarried children under 21 can be included as derivative beneficiaries. They get the same preference category and the same priority date, so they don’t wait in a separate line.³¹²

The risk with a wait this long is aging out. A grandchild who was 10 when you filed may be past 21 by the time a visa number is available, and someone over 21 no longer counts as a “child” for derivative purposes. The Child Status Protection Act (CSPA) softens this. It calculates an adjusted age: the beneficiary’s age when the visa becomes available, minus the number of days the I-130 was pending, equals the CSPA age.¹³

So a derivative who is 23 when a visa number opens, on a petition that sat pending for three years before approval, has a CSPA age of 20 and still qualifies. There’s a catch: the beneficiary must “seek to acquire” the visa within one year of it becoming available. Filing Form I-485 (if adjusting status inside the U.S.) or applying at a consulate abroad satisfies that requirement.¹³

What Happens Once the Priority Date Is Current

When USCIS approves the I-130 and your child’s priority date becomes current, the case moves to the National Visa Center for fee collection, the DS-260 immigrant visa application, and civil document review. If your child lives abroad, the case is routed to a U.S. embassy or consulate for an immigrant visa interview. If your child is already in the United States and was lawfully admitted, they may instead file Form I-485 to adjust status without leaving the country, provided a visa number is immediately available.¹⁴

Before the consular interview, your child completes a medical exam with an embassy-approved physician. At the interview, a consular officer verifies the family relationship and checks for grounds of inadmissibility like criminal history, health concerns, or security issues. Your child brings a valid passport with at least six months of remaining validity, two passport-size photos, original civil documents with photocopies, and the sealed medical results.¹⁵

If the visa is approved, it’s placed in the passport and is generally valid for up to six months from issuance, though an earlier-expiring medical exam can shorten that window. Your child must enter the United States before the visa expires. At the port of entry, a CBP officer admits them as a lawful permanent resident, and the physical green card is mailed to their U.S. address, with USCIS estimating delivery within 90 days.¹⁶¹⁷
