Anyone who has been convicted of a Crime of Moral Turpitude (“CIMT”), will require an immigration waiver to enter the U.S.   CIMTs commonly involve elements of fraud, larceny, or intent to harm persons or things.
CIMTs can be committed against property, governmental authority, people, family relationships, and sexual morality.  They also include intentional distribution of controlled substances; attempts, aiding and abetting, accessories to crimes and conspiracy to commit a CIMT.
CIMTs include fraud, arson, blackmail, burglary, embezzlement, extortion, false pretenses, forgery, malicious destruction of property, receiving or transporting of stolen goods, robbery, larceny, theft, bribery, counterfeiting, mail fraud, perjury, harboring of fugitives, tax evasion, abandonment of children, assault with intent to kill, assault with intent to commit rape, assault with intent to cause serious bodily injury,  assault with a deadly weapon, bigamy, contributing to the delinquency of a minor, gross indecency, incest, kidnapping, lewdness, manslaughter, murder, pandering, possession of child pornography, prostitution, and rape.
While the above-listed crimes are serious, many individuals find themselves inadmissible to the United States for past convictions involving small-scale theft, simple possession of drugs (including marijuana), and assault.  Many people make mistakes in their younger years only to find a past conviction has been unearthed to haunt them due to increased information sharing between law enforcement agencies.  You may view a short video on the topic by clicking here.
