For how long will my visa be valid?
The length of time a visa will continue to be valid will depend on the type of visa you are using, which in turn will be determined by your reason for traveling to the United States. It will also vary depending on your country of citizenship. If you already have a visa, you can check the visa expiration date which is found on your visa near the visa issuance date. The visa expiration date will tell you when your permission to travel to a port-of-entry in the United States under that visa ends.
