Many criminal offenses can deny a person entry into the United States, including murder, rape, child abuse, aggravated assault or multiple misdemeanor convictions, states the U.S. Customs and Border Patrol. Entrance is denied for any drug-related conviction.
Travelers may be able to get a waiver of an entrance denial if the crime was committed years ago. The applicant may petition her embassy in order to expunge the offense or gain a waiver from The Office of Consular Affairs, according to the U.S. Customs and Border Patrol. In general, any crime that is committed maliciously or hurts others either directly or indirectly may warrant the denial of entrance into the country.
The serious crimes against persons mentioned above are considered "crimes of moral turpitude" and may deny entrance to an applicant, according to Nolo. Minor offenses, such as conviction for driving under the influence or while intoxicated, may not deny an applicant entrance, but multiple convictions of the minor violation may do so. Crimes of Moral Turpitude can be classified as either misdemeanors or felonies, depending upon the discretion and laws of the state or municipality charging the individual. Nolo recommends consulting an attorney with any questions on specific circumstances regarding immigration.
