Fiancé(e) Visas (K-1 Visas)

U.S. citizens may petition with U.S. Citizenship and Immigration Services for a fiancé(e) K-1 non-immigrant visa for his/her foreign-citizen fiancé(e). Additional information about the fiancé(e) visa is also available at the Department of State’s website.


How to Apply

Step 1: U.S. Citizen Petitioner Files a Petition with USCIS

Step 2: The National Visa Center

Once USCIS approves the petition, it is sent to the National Visa Center (NVC).   The NVC will assign a case number and send the petition to U.S. Embassy Bangkok’s Immigrant Visa (IV) unit.

Tracking Your Case

You may track the progress of your case from NVC to the IV unit, and within the IV unit at Visa Status Check. The IV unit is only able to respond to inquiries once the cases have been transferred to our office. Therefore, you should first determine where your case is in order to contact the appropriate office.

Step 3: Applicants Must Submit Required Documents and an Interview is Scheduled (Packet3)

Once the IV unit,BKK  receives the case from NVC, US Embassy BKK will contact the applicant with the Packet 3 Instructions.

Please read the instructions carefully, make the application fee payment, and submit all documents to U.S. Embassy Bangkok’s Immigrant Visa unit.

Once the Packet 3 documents are received and the case is determined to be documentarily ready, the IV unit will schedule the applicant’s immigrant visa interview.

The applicant will be informed via email through the Packet 4 Appointment Packet which provides further guidance on additional required documents including the medical examination.


IV Mailing and Contact Information
Pre-interview (non-NVC cases) and post-interview documents should be sent to:

U.S. Embassy Bangkok
Consular Section, Immigrant Visa Unit
120-122 Wireless Road, Lumpini
Bangkok 10330

Step 4: Fiancé(e) Visa Interview and After the Interview

All fiancé visa applicants, including follow-to-join children, must appear in person for their respective interview at U.S. Embassy Bangkok. Applicants should review the Packet 4 checklist prior to the appointment to ensure they have all required documents (including original or certified documents not previously submitted), including passports and their appointment letter. Please review the security regulations to gain entry to the Consular Section.

Important Notes:


Step 5: Visa Issuance

The validity of an fiancé visa is tied to the validity of the applicant’s medical examination report. Therefore, if you plan to travel to the United States after the expiration date of your medical exam, you will need to complete a new medical exam that is valid during that travel period.

After the visa is approved, the visa package will be mailed to the applicant’s address registered on his/her GSS profile within 7-10 business days. Please ensure that you register your address on the GSS website correctly and update any changes before your interview. Remember to print out and submit the GSS address registration confirmation page to the IV unit with your Packet 3 documents. Applicants are reminded not to purchase plane tickets or make any other plans until the visa package, including passport and U.S. visa, is received.

Step 6: Before Traveling to the United States

  • Check your visa package and information on the immigrant visa.
  • DO NOT open the sealed packet. You must carry the sealed visa packet with you when you travel. The U.S. Customs and Border Protection (CBP) officer at the U.S. port of entry will open this package and examine the documents inside.
  • Travel within the visa validity period. You can use the existing visa to travel to the United States until the expiration date.
