What happens if I am denied re-entry to the U.S. after a brief visit to Canada or Mexico because I am a citizen of a designated terrorist sponsoring state without a valid visa?
If you are denied re-entry as a citizen of a designated terrorist sponsoring state without a valid visa, your options are limited. You may apply for the appropriate U.S. visa in your home country. You may be ineligible to apply for the visa in Canada or Mexico (please see below). You may also attempt to obtain deferred inspection, parole, or a documentary waiver at the U.S. port-of-entry, but recent CIS policy changes make this highly unlikely. It is important to remember that expedited removal from the U.S. may be triggered if certain documentary requirements are not met. If this occurs, you may then be barred from the U.S. for many years.
