Question: how long is a us visit visa valid?
Answer: As with other non-immigrant U.S. visas, a B-1/B-2 visa has a validity period (from 1 month to 10 years), allows for one, two, three or multiple entries into the U.S., and elicits a period of stay (maximum 6 months) recorded by the Customs and Border Protection officer at the port of entry on the individual's form I-94.
