Bringing Parents, Children, and Siblings to the U.S.

Direct answer: A U.S. citizen can petition for a spouse, parent, unmarried or married child, or sibling. A green-card holder (lawful permanent resident) can only petition for a spouse and unmarried children. Spouses, minor children, and parents of citizens are "immediate relatives" and face no annual cap, so they're usually the fastest route. Everyone else - siblings, married children, and adult unmarried children - falls into a numerically limited "family preference" category, and the wait is driven entirely by your place in line on the Department of State's Visa Bulletin. For siblings and adult children, that wait can run many years, sometimes decades, depending on the category and country. Always check the current Visa Bulletin and uscis.gov before relying on any specific timeframe, since these move every month and change with policy.

Who can petition whom

The starting point is Form I-130, Petition for Alien Relative, filed by the U.S. citizen or lawful permanent resident sponsor. Eligibility depends on the sponsor's own status:

If the sponsor is a U.S. citizen

• Spouse
• Unmarried child under 21
• Unmarried son or daughter 21 or older
• Married son or daughter (any age)
• Parent (only once the citizen sponsor is 21 or older)
• Sibling (only once the citizen sponsor is 21 or older)

If the sponsor is a lawful permanent resident (green-card holder)

• Spouse
• Unmarried child under 21
• Unmarried son or daughter 21 or older

Green-card holders cannot petition for parents, married children, or siblings. This is a firm rule in the Immigration and Nationality Act, not a policy detail that changes often - but confirm current eligibility categories on the USCIS family immigration page before filing, since supporting requirements and forms are periodically updated.

Immediate relatives vs. preference categories

This distinction determines almost everything about the timeline.

Immediate relatives - no annual cap

Spouses of U.S. citizens, unmarried children under 21 of U.S. citizens, and parents of U.S. citizens (once the citizen is 21+) are "immediate relatives." Congress does not cap the number of immediate-relative visas issued each year, so there's no backlog created by a queue - the case moves as fast as normal processing allows once the petition is approved and the required steps (adjustment of status with Form I-485, or consular processing with Form DS-260) are complete.

Family preference categories - numerically capped

Everyone else falls into one of these preference categories, each with its own annual cap and per-country limits:

• F1 - Unmarried sons and daughters (21+) of U.S. citizens
• F2A - Spouses and unmarried children (under 21) of lawful permanent residents
• F2B - Unmarried sons and daughters (21+) of lawful permanent residents
• F3 - Married sons and daughters of U.S. citizens
• F4 - Siblings of U.S. citizens (petitioner must be 21+)

Because these categories are capped, a visa isn't available the moment the petition is approved - it's available when your priority date (the date USCIS received the I-130) becomes current under the monthly Department of State Visa Bulletin. Demand is much higher than supply in some categories and countries, which is why sibling (F4) and adult-child (F1, F2B, F3) cases can sit in line for many years. Wait times differ significantly by the beneficiary's country of chargeability - some countries have much longer backlogs than others - and they shift from month to month. Do not rely on a wait-time figure from a blog, a forum, or an older article; check the current Visa Bulletin directly.

Aging out and the Child Status Protection Act (CSPA)

"Child" for immigration purposes generally means unmarried and under 21. If a child turns 21 while a petition is pending in a backlogged category, they can "age out" - losing their place as a child and either shifting to a slower category (like F2B) or losing derivative eligibility on a parent's petition entirely.

The Child Status Protection Act can protect against this by allowing part of the time a petition was pending to be subtracted from the child's biological age, producing a "CSPA age" that may keep them classified as a child past their real 21st birthday. Under a USCIS policy that took effect August 15, 2025, the calculation ties visa availability to the Department of State's Final Action Dates chart in the Visa Bulletin (USCIS had used the earlier "Dates for Filing" chart for adjustment-of-status applicants from February 2023 until that change, and it generally applies that prior approach to adjustment applications that were already pending before August 15, 2025). The beneficiary must also show they "sought to acquire" the green card within one year of when a visa becomes available. Because the formula involves exact filing dates, approval dates, and visa-availability dates - and because USCIS has changed this policy before and may again - do not assume a child is or isn't protected on your own. Check the current USCIS CSPA page and, given the stakes, have an immigration attorney or accredited representative confirm the calculation for your specific case.

What to do - basic steps

1. Confirm your own status (U.S. citizen or lawful permanent resident) and the exact relationship to the relative you want to petition for.
2. File Form I-130, Petition for Alien Relative, with supporting evidence of the relationship (birth certificates, marriage certificates, etc.) and evidence of your own status.
3. Track the priority date. If your relative is an immediate relative, there's no queue to watch. If they fall into a preference category, watch the monthly Visa Bulletin for your category and country.
4. Wait for visa availability under either the Visa Bulletin's Dates for Filing or Final Action Dates chart, as USCIS or the National Visa Center instructs for your case.
5. Complete the final step - either adjustment of status (Form I-485) if the relative is already in the U.S. and eligible, or consular processing (Form DS-260 through the National Visa Center and a U.S. embassy or consulate) if abroad.
6. Watch deadlines closely once a visa is available. There are hard timing requirements at several points - responding to National Visa Center document requests, the CSPA "sought to acquire" window, and any deadlines on a Request for Evidence - and missing them can force you to start over or lose eligibility.
7. Re-verify current fees, forms, and processing steps on uscis.gov immediately before filing, since fee schedules and form editions change.

A note on fees, wait times, and changing rules

This article deliberately does not state specific filing fees, processing times, or current priority-date cutoffs, because these change frequently and a stale number can lead someone to misjudge their case. Before filing or making decisions based on a wait-time estimate, check:

• uscis.gov for current forms, fees, and eligibility rules
• travel.state.gov for the monthly Visa Bulletin and priority-date movement
• justice.gov/eoir if a case is in immigration court

Beware of notario and immigration-consultant fraud

No one can legitimately move you ahead of the numerical line or guarantee a faster outcome outside the normal process. Be cautious of "notarios," unlicensed immigration consultants, or anyone charging large fees for guaranteed results - this is a well-documented source of fraud against immigrant families. Get help only from a licensed immigration attorney or a representative accredited through the Department of Justice's recognition and accreditation program (searchable through the EOIR).

This article provides general information, not legal advice, and does not create an attorney-client relationship. Because family immigration cases involve strict deadlines and category rules where a mistake can mean years of delay or loss of eligibility, consult a qualified immigration attorney or a DOJ-accredited representative about your specific situation.
