What Are the Family-Based Green Card Preference Categories (F1, F2A, F2B, F3, F4)?
By Pinal Dave Last updated: 2026-08-01
TL;DR: The F1 through F4 categories are the four "family preference" tracks for relatives who are not immediate relatives of a U.S. citizen. F1 covers unmarried adult children of citizens, F2A and F2B cover spouses and children of green card holders, F3 covers married children of citizens, and F4 covers siblings of citizens. All four are capped annually and tracked by priority date on the visa bulletin, unlike immediate-relative cases which have no cap.
The Core Distinction
U.S. family-based immigration splits into two buckets:
- Immediate relatives of U.S. citizens (spouses, unmarried children under 21, and parents) — no annual numerical limit, so no waiting line once the petition is approved and the case is otherwise ready.
- Family preference categories (F1–F4) — a fixed number of visas issued per year, further split by country, which is why some categories (especially for high-demand countries) show priority dates far in the past on the monthly Visa Bulletin.
The Four Preference Categories
| Category | Who qualifies | Petitioner |
|---|---|---|
| F1 | Unmarried sons and daughters (21+) of U.S. citizens | U.S. citizen parent |
| F2A | Spouses and unmarried children (under 21) of green card holders | Lawful permanent resident |
| F2B | Unmarried sons and daughters (21+) of green card holders | Lawful permanent resident |
| F3 | Married sons and daughters of U.S. citizens | U.S. citizen parent |
| F4 | Brothers and sisters of U.S. citizens (petitioner must be 21+) | U.S. citizen sibling |
F4 (siblings) is consistently the category with the longest waits because it sits lowest in sponsorship priority and draws high demand from a handful of countries with large per-country backlogs.
How a Case Moves Through These Categories
- Petitioner establishes eligibility. The U.S. citizen or green card holder confirms their status and the qualifying family relationship.
- File Form I-130. This establishes the relationship and assigns a priority date — the date USCIS receives the petition, which becomes the case's place in line.
- USCIS approves the I-130. Approval confirms the relationship is valid; it does not by itself grant a visa or green card.
- Wait for the priority date to become current. Check the Department of State Visa Bulletin each month against the category and country of chargeability (usually the applicant's country of birth).
- Consular processing or adjustment of status. Once current, the relative applies for an immigrant visa abroad through the National Visa Center and a U.S. consulate, or files Form I-485 if already lawfully present in the U.S. and eligible to adjust.
Why Priority Dates Move at Different Speeds
Each category has its own annual allocation, and each country also has a per-country cap regardless of category. Countries with historically high demand — commonly Mexico, India, China, and the Philippines — can have separate, slower-moving priority dates within the same category than the rest of the world. This is a structural quota mechanism, not a reflection of processing effort on any individual case.
FAQ
What happens to an F2A case if the petitioner naturalizes? The case can convert to the immediate-relative category if the beneficiary is the naturalized citizen's spouse or an unmarried child under 21, which generally removes the annual cap and can speed up the case. A conversion request or automatic upgrade may apply depending on the specific facts.
What happens to an F1 case if a beneficiary gets married? Marriage generally moves an unmarried son or daughter of a citizen out of F1 and into F3 (married sons and daughters of citizens), which has its own separate visa bulletin line.
Can a beneficiary work or travel while a preference petition is pending? Simply having an approved I-130 does not grant work authorization or travel permission. Those benefits generally attach only once the person has a pending adjustment of status application with the corresponding EAD/advance parole application, or holds a valid nonimmigrant status separately.
Is there a way to expedite a preference category case? USCIS has narrow expedite criteria for severe humanitarian or other qualifying circumstances, but there is no standard way to pay for faster preference-category processing the way premium processing works for some employment-based petitions.
Does the priority date ever move backward ("retrogress")? Yes. If demand in a given month exceeds the annual allocation, the State Department can move a category's priority date backward temporarily, which is different from the date simply not advancing.
Which category should I check if my sibling is a U.S. citizen and I am unmarried? That would generally be F4, since F4 covers siblings of citizens regardless of the beneficiary's marital status, provided the citizen petitioner is at least 21 years old.
