This bill proposes significant changes to immigration law by establishing new grounds for inadmissibility and deportability related to driving while intoxicated or impaired offenses. It specifically amends the Immigration and Nationality Act to include these provisions, aiming to strengthen enforcement against such conduct. Under the proposed changes, an alien would be deemed inadmissible if they have been convicted of, admit to committing, or admit to acts constituting the essential elements of a driving while intoxicated or impaired offense. This includes driving under the influence of alcohol or drugs, and applies irrespective of whether the offense is classified as a misdemeanor or a felony. Furthermore, the bill stipulates that any alien convicted of such an offense would be considered deportable, without regard to the offense's classification as a misdemeanor or felony.
