F1 and F3 visa categories are family-sponsored immigrant visa petitions that may be filed by a U.S. Citizen. An F1 visa petition is filed for unmarried sons and daughters, while an F3 petition is for married sons and daughters.
Visa Category Conversion: When Does It Happen?
Visa category conversions happen when there are changes in certain personal circumstances of petitioners or beneficiaries.
F1 – F3 Conversion
When the beneficiary who is being petitioned under the F1 visa category marries, the original F1 petition will be converted to the F3 visa category, also retaining the same priority date. If the beneficiary subsequently terminates that marriage, the petition will be reclassified to the F1 category.
