How to Apply

Step 1: Potential Employer Files a Petition with USCIS

Step 2: Applicants Must Submit Required Documents and an Interview is Scheduled

Once your petition is approved, it will be further processed for an immigrant visa:

2(a) Petitions filed in the United States: Please follow instructions provided by the National Visa Center (NVC) as the requested documents must be submitted to their office. Once NVC has received all required documents and fees, NVC will schedule the applicant’s immigrant visa interview at U.S. Embassy Bangkok.


  • Be sure to keep a record of the NVC receipt number once payment is made. You will need this number to complete the DS-260 process. The IV unit does not have records of these receipt numbers and you will need to follow up with NVC to obtain it should you lose it.
  • Your case will not be transferred to the IV unit until the NVC process is completed. You may track the progress of your case from NVC to 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.

2(b) Petitions filed with the USCIS Bangkok Field Office: Once the IV unit receives the case, our staff will contact the applicant with the IV Packet 3 (Pre-Interview) Instructions. Please read the instructions carefully and submit all documents to U.S. Embassy Bangkok’s Immigrant Visas 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.
