When does your U.S. visa expire?
If the traveler already has a U.S. visa appropriate for this travel, check the expiration date on the visa to make sure it will not expire before the planned travel date.
When does your passport expire?
In order to obtain a U.S. visa, your passport must be valid for at least six months beyond your period of stay in the United States, unless exempt by country specific agreements.
When should you apply for a U.S. nonimmigrant visa?

Recent media reports have indicated that the Administration has instructed U.S. Consulates to request additional documentation from applicants for visas to the United States. This may include information concerning travel and work history as well as other details. We encourage travelers to familiarize themselves with these reports and factor in additional time for visa processing. For the latest information on U.S. visas, please visit the U.S. Department of State website.
How should you apply for a U.S. nonimmigrant visa?
Visit the website of the local U.S. Embassy or Consulate in your country to find out the process for applying for a U.S. visa, and how long it will take.
Additional planning time beyond the guidelines above may be needed for visa applicants applying at some embassies because of the time required to schedule an interview appointment. Additionally, the wait times for a Nonimmigrant Visa do not include time for required security clearances or administrative processing, which may extend beyond the general timeframe guidelines.
