How may an individual in a valid nonimmigrant status obtain or extend the validity of the visa in his or her passport?
Generally, individuals wishing to apply for nonimmigrant visas must make a personal appearance before a U.S. consular officer at a U.S. Embassy or Consulate outside of the U.S. In certain instances, an individual may have her/his visa revalidated in the U.S. This is done by application to the U.S. Department of State. This option is available only if the individual’s passport already has a recently expired or expiring H, L, 0, P, or E visa previously issued at a U.S. Embassy or Consulate. Detailed information about visa revalidation is available on the web site of the Department of State.
