On April 27, 2011 the United States Department of State issued their final ruling pertaining to non-immigrant visa revocation. Now U.S. Consular Officers and U.S. embassies and consulates abroad have more authority to revoke non-immigrant visas that had been previously issued. This change will particularly affect those traveling to the United States for business or extended travel. As of now, the consular officer’s power only extends to temporary revocation, although authority to revoke visas permanently is under consideration. This change in policy is brought on by what the Department of State describes as “security concerns,” although a number of situations could come about where visa revocation is necessary even without any security concerns. Reasons for this could be changes in job title, salary, or location, as well as the addition of another job. Once a non-immigrant visa has been revoked, the foreign national will be notified of the revocation . The visa then will be entered into the Consular Lookout and Support System (CLASS) and will no longer be valid. This increase in power granted to consulates makes it necessary for foreign nationals to take certain precautions before traveling abroad.
