Drivers in South Carolina who have been convicted of a DUI face a variety of consequences including fines, jail time, license suspension, alcohol classes and community service. On top of all that, a DUI can also affect them in a number of other ways, such as travel.
One of the travel consequences that may have a major effect on some travelers, which is stated by the U.S. Customs and Border Protection, is denied entry into Canada. This decision is up to the immigration officer when one arrives at the port of entry or applies for an Electronic Travel Authorization or a visa.
The Collateral Consequences Resource Center reports the reason Canada is able to determine if someone has a DUI or other criminal offense is because the Canada Border Services Agency has direct access to the National Crime Information Center. Other countries are not able to access this database on an immediate basis, so presenting your passport for entry does not affect travelers in the same way. However, a DUI may be an issue in regard to applying for a visa in another country, as questions about criminal activity are asked on the application.
Travelers who fly internationally on a frequent basis will be affected by their DUI if they apply for Global Entry or other pre-cleared border crossing travel program. Applicants undergo an intense interview and background check during the application process, and they are denied enrollment for anything that deems them a high risk, such as any criminal activity.
