How Does a U.S. Citizen Get a Green Card for a Child?

An unmarried child under 21 of a U.S. citizen is an immediate relative under the Immigration and Nationality Act, which means no annual visa cap and no Visa Bulletin wait. The green card for a child of a U.S. citizen is called IR-2 when it is issued at a consulate; inside the United States the same child adjusts status on Form I-485. It is the simplest category in family immigration, but it still has rules that trip up parents: one petition per child, a strict definition of who counts as a child, and a 21st birthday that can change everything. CLP’s green card for children practice handles these filings; this article explains what the process looks like from the parent’s side.

Who qualifies for a green card as the child of a U.S. citizen

Section 101(b)(1) of the INA defines “child” more narrowly than everyday usage. The child must be unmarried and under 21 and must fit one of these relationships:

• Born in wedlock to you.
• Born out of wedlock. A mother qualifies on the birth certificate alone. A father must show legitimation before 18, or a bona fide parent-child relationship before the child turned 21 (support, contact, acknowledgment).
• Your stepchild, if you married the child’s parent before the child turned 18. Our post on sponsoring a stepchild for a green card covers that rule in detail.
• Your adopted child, if the adoption was final before age 16 and you have had two years of legal custody and two years of joint residence. Children adopted abroad usually immigrate through the Hague process (Forms I-800A and I-800) or the orphan process (Forms I-600A and I-600) instead of a plain I-130.

If your child is 21 or older and unmarried, the petition falls into the F1 preference category and waits for a priority date. If your child is married at any age, it is F3. Both wait for a priority date under the Visa Bulletin.

Step one: file Form I-130 for each child

Each child needs their own Form I-130. Immediate relative petitions do not carry derivatives, so a citizen sponsoring a spouse and two stepchildren files three separate petitions, each with its own filing fee and evidence set. The core evidence is proof of your citizenship and the child’s birth certificate naming you, plus the marriage certificate, legitimation evidence or adoption decree that fits the relationship, with certified English translations. For the form itself, see our guide to Form I-130.

The filing date matters more than most parents realize. Under the Child Status Protection Act, an immediate relative child’s age is frozen on the day USCIS receives the I-130. A child who is 20 years and 11 months old on the receipt date stays “under 21” for the whole case. A child who turns 21 before you file loses that protection and drops into F1. If a birthday is close, file now and supplement the evidence later. We explain the full formula in our post on how the CSPA age calculation works.

Step two: adjustment of status or an immigrant visa

Where your child is, and how they got there, decides the second half of the case.

If your child is in the United States after a lawful admission (a visitor visa, a student visa, even one that has since expired), you can usually file the I-485 together with the I-130. Immediate relatives are forgiven an overstay and unauthorized work for adjustment purposes, so the expired status does not bar the green card. The concurrent filing includes the medical exam on Form I-693, biometrics, and the affidavit of support. Our walkthrough of Form I-485, step by step covers the packet.

If your child entered without inspection, adjustment is generally unavailable and the case ends at a U.S. consulate. A child who is 18 or older with more than 180 days of unlawful presence may need a provisional waiver on Form I-601A before leaving, because departure triggers a reentry bar.

If your child is abroad, USCIS approves the I-130 and transfers it to the National Visa Center, which collects the DS-260, civil documents and your Form I-864, then schedules the interview at the embassy or consulate. Our family reunification page describes that consular stage. The child enters on the immigrant visa and becomes a permanent resident at the port of entry.

The affidavit of support and the citizenship shortcut

Most parents sign Form I-864 showing household income at or above 125 percent of the Federal Poverty Guidelines for their household size, with a joint sponsor if needed. There is an exception that often applies to young children. Under section 320 of the INA, a child under 18 who is admitted as a permanent resident and lives in the legal and physical custody of a U.S. citizen parent becomes a citizen automatically. Because that child will not remain a permanent resident, the parent files Form I-864W, a request for exemption, instead of the full affidavit.

Check two other routes before you start. A child born abroad to a U.S. citizen parent may already be a citizen at birth, depending on the parent’s prior physical presence in the United States. A child under 18 living abroad may qualify for naturalization on Form N-600K through a citizen parent or grandparent. Our citizenship and naturalization page covers those options; when one of them applies, the green card is unnecessary.

What slows these cases down

Processing times move with USCIS workloads and the office involved, so check the current USCIS processing times. The delays you can control are these:

• A father petitioning for a child born out of wedlock without legitimation or relationship evidence. USCIS will issue a Request for Evidence, and sometimes a DNA test request.
• A stepchild petition where the marriage took place when the child was already 18. There is no step relationship under immigration law in that case.
• An I-864 that does not meet the income threshold, with no joint sponsor lined up.
• A missed medical exam or an expired vaccination record at the interview.
• A child who marries before the green card is issued. Marriage ends immediate relative status and moves the case to F3, with a wait measured in years.

If your child is approaching 21 or your family situation is unusual, a short consultation with Capitol Law Partners can confirm the category and the right filing sequence before you submit anything. Schedule a consultation.
