K3 visa


The K-3 visa classification applies to a Thai individual person who is already married to a U.S. citizen. It allows the applicant to enter the U.S. to join his or her U.S. citizen spouse and wait in the U.S. to complete the lawful permanent residence process.

To qualify for a K-3 visa, the applicant must:

(1) Be legally married to a U.S. citizen and

(2) Be the beneficiary of an immigrant Petition for Alien Relative, Form I-130 filed by his or her U.S. citizen spouse.

Petition Processing

The K visa application process begins with the U.S. citizen spouse filing both an Immigrant Petition for Alien Relative, form I-130, and a Petition for Alien Fiancée (e), form I-129F, on behalf of his or her foreign born spouse with U.S. Citizenship and Immigration Services (USCIS). USCIS will adjudicate and forward the approved K petition filed by the U.S. Citizen to the designated consular post where the K applicant lives. The K visa applicant will then attend a scheduled visa interview at the consulate to complete the application process.

A K-3 visa is valid for two years and for multiple entries into the U.S.

K-3 visa holders are eligible to apply for work authorization upon arrival in the U.S. based on their K status. They may also separately apply for work authorization and a travel permit when applying for lawful permanent residence.

The unmarried children, under the age of 21, of a K-3 visa applicant are eligible to apply for K-4 dependent status.

Permanent Residence

Following their entry into the U.S., K-3 visa holders can apply for lawful permanent residence by filing an application with USCIS. However, they cannot apply to change their status from K non-immigrant status to any other non-immigrant status or to extend their K-3 status.

A K-3 visa holder has up to two years to apply for U.S. permanent residence, although he or she may initiate the permanent residence process immediately upon entering the U.S.
