The family-sponsored side of the Visa Bulletin is organized into four numbered preference categories, plus the F2A sub-category, and each one has its own pace, its own demand level, and its own typical wait time. This guide explains what F1, F2A, F2B, F3, and F4 actually mean so you can find your case and understand roughly where it sits in line.
Family Preference Categories at a Glance
F1 covers unmarried adult sons and daughters of U.S. citizens. F2A covers spouses and unmarried children under 21 of lawful permanent residents. F2B covers unmarried adult sons and daughters of lawful permanent residents. F3 covers married sons and daughters of U.S. citizens. F4 covers brothers and sisters of adult U.S. citizens. Immediate relatives of U.S. citizens, meaning spouses, unmarried children under 21, and parents, are not part of this numbered system at all, since they are not subject to an annual cap and do not appear on the Visa Bulletin.
F1: Unmarried Sons and Daughters of U.S. Citizens
F1 is for adult children, 21 or older, of U.S. citizens who have never married. Because a child of a U.S. citizen who is still unmarried and under 21 already qualifies as an immediate relative with no wait, F1 exists specifically for those who have aged out of that category or were always over 21 when the petition was filed.
F2A and F2B: Family of Green Card Holders
F2A and F2B both cover relatives of lawful permanent residents rather than citizens, which is why they generally move faster than F1, F3, or F4. F2A, for spouses and unmarried children under 21, usually has the shortest wait of all the numbered family categories and even reaches “current” status in some months. F2B, for unmarried sons and daughters 21 or older of green card holders, moves more slowly than F2A but is still generally faster than F1, F3, or F4.
F3: Married Sons and Daughters of U.S. Citizens
F3 covers married children of U.S. citizens of any age. Because marriage removes eligibility from the faster immediate relative and F1 categories, F3 tends to carry one of the longer wait times on the family side, particularly for applicants born in Mexico and the Philippines.
F4: Siblings of U.S. Citizens
F4 is for brothers and sisters of adult U.S. citizens, and it is consistently the slowest-moving family category, often carrying waits of well over a decade, and even longer for India, Mexico, and the Philippines. The petitioning U.S. citizen must be at least 21 years old to file an F4 petition.
Frequently Asked Questions
Which family category moves the fastest?
F2A, for spouses and minor children of green card holders, is typically the fastest-moving numbered family category and occasionally becomes current for all countries.
What happens if my F2A child turns 21 while waiting?
The Child Status Protection Act may allow the child’s age to be “frozen” at the time the priority date became current, in certain circumstances, so the case does not automatically move to the slower F2B category. This calculation is fact-specific and worth reviewing carefully.
Why is F4 so much slower than the other categories?
F4 has one of the lowest annual allocations among family categories and represents the most distant relationship recognized in family-sponsored immigration, so demand consistently exceeds supply by a wide margin, especially from high-demand countries.
Final Thoughts
Knowing exactly which family preference category your petition falls into is the first step to reading the Visa Bulletin correctly, since each row moves at its own pace.
