The time it takes for your application to be approved depends on many factors, among them what type of visa, which U.S. consulate you are using, and whether your application will be subject to an additional security clearance check.
In general, most U.S. visas are approved and issued within seven to ten business days, though some can take longer.
Visa processing delays can occur where the consular official at the visa interview determines that further screening is necessary before the visa can be issued. The consular officer will indicate that the application must undergo administrative processing.
Applications are subjected to administrative processing for various reasons, including but not limited to:
If your application is subject to administrative processing, you should receive a document from the consular officer advising you of the additional processing for your application, and providing you with instructions for checking the status of your application.
Your visa processing could take anywhere from two weeks to several months. There is no mechanism to expedite the process, but if you find yourself in this situation be sure to contact your OVIS advisor and your department at Dartmouth. OVIS can make an inquiry with the Department of State 60 days after the date of your visa interview.
If your visa application is denied, the consular official should provide you the reason for the denial. Contact your OVIS advisor if your application is denied to determine your options.
It is important to know that the Department of State can revoke your visa if you violate a federal or state law in the U.S. If you are arrested for “driving under the influence” of alcohol, that charge can lead to the revocation of your visa, and you would be required to apply for a new visa at a U.S. Consulate before you could re-enter the U.S. after a departure.
