U.S. citizens and lawful permanent residents (LPRs) both file the same form — USCIS Form I-130, Petition for Alien Relative — to start the family-based immigration process. But the list of relatives each can sponsor, and how long those relatives wait once the petition is approved, look almost nothing alike.
What changed
The petitioner-eligibility framework comes directly from the Immigration and Nationality Act, and USCIS adjudicators work it day to day out of Policy Manual Volume 6, Part B. Two statutory provisions do most of the heavy lifting.
INA §201(b)(2)(A)(i) (codified at 8 U.S.C. §1151) carves out the “immediate relative” category for spouses, unmarried children under 21, and parents (when the citizen petitioner is at least 21 years old) of U.S. citizens. Immediate relatives are not subject to numerical limits. No preference category, no Visa Bulletin wait, no per-country cap. If the petition is approved and the beneficiary is otherwise admissible, a visa number is available the day the case is ready.
INA §203(a) (8 U.S.C. §1153) governs the four family-preference categories. Each is numerically capped per fiscal year and subject to per-country limits, which is why preference categories backlog:
- F1 — unmarried sons and daughters age 21 and over of U.S. citizens.
- F2A — spouses and unmarried children under 21 of lawful permanent residents.
- F2B — unmarried sons and daughters age 21 and over of lawful permanent residents.
- F3 — married sons and daughters of U.S. citizens (any age).
- F4 — brothers and sisters of U.S. citizens, with the citizen petitioner at least 21 years old.
LPRs are confined to F2A and F2B. An LPR cannot petition for a parent, a sibling, or a married son or daughter. Naturalization is what unlocks F1, F3, F4 and the immediate-relative category. The State Department posts cutoff dates for each preference category every month in the Visa Bulletin.
The procedural rules sit at 8 CFR Part 204 — §204.1 for general petition rules and §204.2 for petitions for spouses, children, parents, and siblings. USCIS Policy Manual Volume 6, Part B, Chapter 2 walks through the petitioner-eligibility analysis adjudicators apply.
Two restrictions apply across petitioner type.
- Age 21 minimum to petition for a parent (citizen) or a sibling (citizen).
- Adam Walsh restriction at INA §204(a)(1)(A)(viii) and §204(a)(1)(B)(i)(II), added by the Adam Walsh Child Protection and Safety Act of 2006 (Pub. L. 109-248). A petitioner who has been convicted of a “specified offense against a minor” is barred from filing unless USCIS determines the petitioner poses no risk to the beneficiary. The check applies whether the petitioner is a citizen or LPR, and it applies to every I-130 — not just petitions for children.
USCIS sets fees by rule. The current schedule, in effect since the 2024 final fee rule took effect April 1, 2024, is $675 for paper I-130 filings and $625 for online filings. Always confirm the current fee against the Form I-130 page before submission — fee rules change.
Why it matters
For mixed-status families, the citizen-versus-LPR distinction is the single biggest variable in case strategy. The same beneficiary can be:
- an immediate relative with no wait, eligible to file Form I-485 concurrently with the I-130 if physically present in the United States in a lawful status; or
- an F2A preference beneficiary subject to whatever the State Department posts in this month’s Visa Bulletin.
Naturalizing the petitioner is often the highest-leverage move counsel can make. An LPR spouse petitioning for a foreign-national spouse files F2A. The same petitioner, post-naturalization, files IR-1. The beneficiary’s case can move from “wait for the chart” to “file concurrently next month.”
The math on the preference categories is unforgiving. F4 — siblings of U.S. citizens — is the most backlogged category in the system, with the rest-of-world final-action dates routinely sitting more than 15 years behind the filing date and Mexico and the Philippines stretching further still. A sibling petition filed today is a multi-decade promise; that conversation belongs in the engagement letter, not the cover sheet.
F2A is more volatile. It has spent significant chunks of recent history at “current” but retrogresses without warning when demand spikes. Filing the I-130 immediately preserves a priority date that may turn out to be the difference between adjusting status next year and adjusting status next decade.
There is also a reverse problem. An LPR who naturalizes mid-case can find that a pending F2B petition automatically converts to F1 under INA §203(h)(3) — the Child Status Protection Act opt-out provision discussed in USCIS Policy Manual Volume 7, Part A, Chapter 7 — or to immediate relative for an unmarried child under 21. Sometimes that conversion helps; sometimes the F1 chart is actually slower than the F2B chart for a given chargeability country. Run the math before submitting the N-400.
Way forward
- Confirm petitioner status on the day of filing. A green card in the desk drawer is not the same as current LPR status. Check the I-551 expiration date. For conditional residents under INA §216 (8 U.S.C. §1186a), confirm that Form I-751 was timely filed and the conditional status remains valid — a conditional resident is an LPR and can file an I-130, but the file should note the status.
- Run the naturalization math first. If the petitioner is N-400 eligible, model both timelines: (a) file I-130 as LPR now and upgrade after naturalization, or (b) naturalize first and file as a citizen. For most F2A and F2B cases involving derivative children near 21, option (b) is usually correct because it converts the case to immediate relative and unlocks the CSPA §201(f) age freeze. But not always — for some F2B chargeability combinations the F1 chart is slower than F2B. Check the current Visa Bulletin before recommending.
- Screen for Adam Walsh exposure before submission. Any prior conviction involving a minor — even decades old, even expunged — must be analyzed under INA §204(a)(1)(A)(viii). USCIS runs the criminal-history check regardless of disclosure; surprises at the RFE stage cost months and sometimes the case.
- File F2A even when the chart is current. A current chart can retrogress at the next monthly bulletin. The priority date is the asset — protect it by filing the I-130 the day the case is documentary-ready, even if no I-485 will be filed concurrently.
- Set sibling-case expectations in writing. For F4, paper the engagement letter with the actual visa-availability horizon and the foreseeable consequences: derivative spouses and children may age out, life circumstances may change, the beneficiary may marry and convert to F3, and the priority date may still not be current. Plain language in the engagement letter prevents the hardest conversations later.
