Overview
U.S. family preference immigration is divided into four categories, allowing U.S. citizens and green card holders to petition for specific relatives. Unlike immediate relative immigration, family preference categories are subject to annual visa number limits, and applicants typically wait years — sometimes over a decade — for a priority date to become current. The four categories are: F1 — unmarried adult children (21+) of U.S. citizens; F2A — spouses and minor children of green card holders; F2B — unmarried adult children (21+) of green card holders; F3 — married adult children of U.S. citizens; F4 — siblings of U.S. citizens. Wait times vary by country of birth and category.
Eligibility by Category
- F1: Unmarried adult children (21+) of U.S. citizens, and their minor children
- F2A: Spouses and unmarried children (under 21) of green card holders (permanent residents)
- F2B: Unmarried adult children (21+) of green card holders
- F3: Married adult children of U.S. citizens, and their spouses and minor children
- F4: Siblings of U.S. citizens, and their spouses and minor children (petitioner must be at least 21)
- All categories require the U.S. citizen or green card holder to file Form I-130 (Petition for Alien Relative)
Application Process
Determine Category
Based on the petitioner's status (citizen or green card holder) and the beneficiary's relationship, determine the applicable F1-F4 category.
File Form I-130
Submit Form I-130 and relationship evidence to USCIS. The filing date establishes the "Priority Date," which determines the applicant's place in line.
Wait for Priority Date
Monitor the monthly Visa Bulletin published by the Department of State, waiting for the priority date to become Current. Wait times vary by category and country of birth.
NVC Processing
Once the date is current, the case transfers to the NVC (National Visa Center). Pay fees and submit Form DS-260 and supporting documents.
Interview / I-485
Attend an immigrant visa interview at a U.S. consulate abroad; or file Form I-485 for adjustment of status within the U.S.
Receive Green Card
After the consular interview is approved, the immigrant enters the U.S. and receives a green card. For I-485, the card is mailed after approval.

Frequently Asked Questions
Are there ways to speed up the long wait?
Strategies include: (1) If a green card holder petitioning for a spouse/child (F2A/F2B) naturalizes as a citizen, the spouse and unmarried children under 21 are automatically reclassified as immediate relatives (no wait); (2) the beneficiary may independently pursue employment-based immigration (e.g., EB-1A, NIW) if eligible; (3) Cross-Chargeability rules — if the beneficiary's spouse was born in a country with shorter wait times, the spouse's country of birth may be used; (4) monitor Visa Bulletin trends, as some years see significant advancement.
How do I maintain status while waiting?
Beneficiaries waiting in the U.S. must maintain valid nonimmigrant status (such as H-1B, L-1, F-1, etc.). If status expires before the priority date becomes current, the beneficiary must depart the U.S. or obtain another visa. Waiting abroad poses no status issues. Some F2A beneficiaries may file I-485 when the priority date is near Current if they maintain lawful status in the U.S.
What if the beneficiary's status changes during the wait?
Status changes can affect classification: (1) if an F1 (unmarried child) beneficiary marries, they are reclassified as F3 (married child), with a longer wait; (2) if an F2B (unmarried child of a green card holder) beneficiary marries, they lose eligibility entirely (green card holders cannot petition for married children); (3) if the petitioner naturalizes from green card holder to citizen, F2A beneficiaries are automatically upgraded to immediate relatives, and F2B beneficiaries are upgraded to F1 (priority date retained). Caution with marriage or other status changes during the wait is strongly advised.
What if a child ages out during the wait?
A child who turns 21 during the waiting period may "age out," causing reclassification to a different (usually slower) category. The Child Status Protection Act (CSPA) provides some protection: CSPA age = actual age when visa becomes available minus I-130 processing time. If the CSPA age is under 21, the child retains the original category. F2A children who age out may be reclassified to F2B (longer wait). Filing I-130 as early as possible to lock in the priority date is strongly recommended.
