5. Prepare for the Consular Interview You must bring documents such as a valid passport, Form DS-160, fee payment receipt, USCIS approval letter, and evidence of the job offer.
6. Attend the Interview and Wait for the Decision During the interview, the consular officer will evaluate your case and decide whether to grant you the visa. If approved, you will receive instructions to pick up your visa and travel to the United States.
