Fiancé(e) Visas (K-1 Visas)

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.

An approved I-129F petition remains valid for four months from the date of USCIS’s approval. Consular officers can extend the validity of the petition (revalidate the petition), and in practice does so while the application is being processed.

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

Once the IV unit receives the case from NVC, our staff 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. Generally, interviews are scheduled within 60 days of receipt of the Packet 3 information, and applicants should refrain from contacting the IV unit to inquire about an interview appointment until 60 days have elapsed from the time the Packet 3 documents were submitted.

You may check our online appointment schedule, updated monthly, to view scheduled appointments for that month. If your appointment is listed on our website but you have not received an Appointment Letter, please download an Appointment Package and follow the detailed instructions. You may schedule your medical appointment directly with the hospital and be permitted entry for your interview without your Appointment Letter.

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(e) 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:

  • Applications incomplete at the time of the visa interview will result in a minimum 10 -15 business day delay in adjudication of your application. Administrative processing required for incomplete applications and other reviews in individual cases may require more time depending on the nature of the review. Therefore, you are strongly advised to have all required documents at the time of your visa interview.
  • Because appointments are set for precise times, appointments for applicants arriving late may be cancelled and rescheduled for a later date. The IV unit strongly advises applicants to be on time for their appointment.   
  • If your medical examination report will not be completed by the time of your interview, please contact the IV unit at as soon as possible to reschedule your appointment.  
  • Please notify us immediately upon the death of the petitioner or an accompanying family member, or if you have a change of marital status, the birth or adoption of a child, or a change of address/e-mail address.  
  • A decision about a visa application cannot be made until an applicant formally applies and is interviewed. Therefore, applicants should NOT make any travel plans, quit their jobs, sell property, or take any other action contingent upon the issuance of an immigrant visa until the applicant has physically received his/her passport and U.S. immigrant visa. 
  • Petitioners are not permitted to attend the interview. Applicants should be familiar with all of the documents they are presenting at the interview, and be able to provide the consular officer with all requested information. An exception is made for immigrant visa applications under the age of 18 who may be accompanied by a parent or legal guardian.

After the interview, if the consular officer requests additional information or documents during your interview, you will need to submit them at Thailand Post document drop-off locations (Bangkok locations or other locations), which will deliver your documents to the Immigrant Visa unit at this address:

U.S. Embassy Bangkok
120-122 Wireless Road
Lumpini, Patumwan
Bangkok 10330

Step 5: Visa Issuance

The validity of an fiancé(e) 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. Please be sure to inform the consular officer so a 221G letter may be provided for directions on how to submit the exam at a later date.

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.
