F3 — Married child of citizen immigration law firms
About the F3 category
The F3 family third-preference category is for the married sons and daughters of U.S. citizens, together with their spouses and minor children, who can be included as derivatives. It is a capped category with multi-year — often very long — waiting times that depend on country of birth. Because the wait spans years, life changes matter: a divorce can move the case to the F1 category, and children who age out or marry can be affected. Accurate initial filing, derivative planning for a spouse and children, and keeping the case current over a long horizon are the practical priorities.
Who the F3 category is for
- You are the married son or daughter of a U.S. citizen.
- Your spouse and minor children can come as derivatives.
- Capped category with long, country-dependent waits.
How the process works
How a family case unfolds: the U.S.-citizen or permanent-resident relative files an I-130 petition that proves the family relationship. For immediate relatives there is no visa-number wait; for the preference categories, the family then waits for the priority date to become current in the monthly Visa Bulletin. Once a visa is available, the relative abroad completes consular processing through the National Visa Center and a U.S. embassy interview, or — if already lawfully in the United States — files for adjustment of status. An affidavit of support is required to show the household can financially sponsor the immigrant, and a medical examination and background checks complete the case.
Common F3 pitfalls
A handful of avoidable problems account for most setbacks in these cases — nearly all of them easier to fix before filing than after:
- Derivative children aging out during a very long wait.
- A divorce mid-process, which can shift the case to F1.
- Incomplete derivative documentation for a spouse and children.

When a law firm helps most
For F3 cases, a law firm offers structure and continuity a case can rely on from the first filing to the final decision. Larger teams can absorb volume, respond quickly to requests for evidence, and coordinate the employer, the applicant and any dependents at once — which matters most when timelines are tight or the stakes are high.

- A clear point of contact — someone named who owns your file and keeps you updated.
- Languages you speak — so nothing is lost between you and your case.
- Transparent pricing — flat or clearly explained fees, agreed before the work begins.
