You are required to contact the U.S. Consulate or. U.S. Embassy in your country to make an appointment for a visa interview at least three months before the.They asked to bring all immigration documents and contract between the employer and the end client. My question is: where should i send the letter? Keep your expectations low. The notice you received does not guarantee you an interview. Offers of admission are valid only for the term indicated in the admittance letter. Accelerate your hiring process. Interview candidates quicker, deliver the best candidate experience, and reduce your time-to-hire. When is the interview?
