In general, a first-time DUI is not a crime involving moral turpitude. However, there have been cases in the Immigration Board of Appeals in which specific factors were acknowledged causing the conviction to rise to the level of a moral turpitude crime, such as children being in the car and causing child endangerment or causing an accident leading to extreme injury.
A second DUI can also affect someone’s consideration for the immigrant’s visa application or visa application in general when they might not satisfy the moral character requirements needed for most if not all, visa applications or immigration benefit applications.
