Once USCIS sends the case file to the National Visa Center (NVC), NVC will contact the petitioner and beneficiary to inform what documents they need to collect from the applicants before scheduling the beneficiary's visa interview at the Consular office at the U.S. Embassy in Rangoon. Please note that on the appointed interview date, if there are any documentary insufficiencies or the medical exam has not been completed, then the case will be administratively refused until all documentary and medical requirements have been fulfilled. The panel physician who performs the medical exams for immigrant visa cases in Rangoon is the International SOS Clinic at the Dusit Inya Lake Hotel, 37 Kaba Aye Pagoda Road. SOS Clinic's phone number is (95-1) 667-879.
On your interview date, bring all the evidence you have that proves your relationship to the petitioner. This may include your birth certificate, family registration, educational degree, national registration card, photos, phone receipts, evidence of communication with the petitioner, and other things. Bring original documents, or duplicates issued by the correct authority if the original is lost. If the petitioner has the original documents in the U.S., have them sent to you to bring to the interview.
Before the interview, you will be asked to take an oath affirming that all the information in your case file, and all the information you tell the Consular Officer during the interview, is true and complete.
