A DUI/DWI conviction is generally not a criminal offense that will lead to deportation of a legal permanent resident (green card holder)—but such a conviction may make it very difficult to become a naturalized U.S. citizen. This is primarily because “good moral character” is a requirement for U.S. citizenship.

And although a DUI/DWI is generally not a deportable offense, a DUI/DWI that (1) is an aggravated felony offense, (2) is related to the illegal use and possession of controlled substances (drugs), or (3) is a crime involving child neglect (which may include a DUI/DWI when there is a child in the vehicle) may be deportable offenses.

And if a person on a student visa—whether an F-1 (academic student) or M-1 (vocational student)—is arrested for DUI/DWI, the temporary, nonimmigrant student visa may be revoked.

In South Carolina, as in other states, a DUI (driving under the influence) or DWI (driving while intoxicated) conviction can have serious immigration consequences, although it is not automatically a deportable offense for legal permanent residents (green card holders). However, such a conviction can impact the assessment of 'good moral character,' which is a requirement for naturalization to become a U.S. citizen. If the DUI/DWI is classified as an aggravated felony, involves illegal drugs, or includes a crime such as child neglect (for example, if a child is present in the vehicle during the offense), it may become a deportable offense. For nonimmigrant visa holders, such as those on F-1 or M-1 student visas, an arrest for DUI/DWI can lead to visa revocation. It's important to note that immigration law is primarily federal, so while state statutes in South Carolina define the DUI/DWI offenses, the implications for immigration status are governed by federal law and handled by federal agencies such as U.S. Citizenship and Immigration Services (USCIS) and the Department of State.
