The U.S. Immigration and Nationality Act (INA) is a complex federal law that relates to naturalization, immigration and the exclusion of aliens. There are many different reasons why an immigrant might be deported from the U.S. and sent back to their country of origin. They might face deportation if they have violated any of the terms of their green card or visa, and grounds for deportation include:
- Conviction for most controlled substances
- Committing marriage fraud
- Knowingly helping to smuggle any alien trying to enter the country
- Committing human trafficking
- Conviction of a crime involving immorality that was committed within five years of residing in the United States
- Violating travel and documentation restrictions
- Conviction of child abuse, domestic violence, or child abandonment, at any time after entering the United States
- Conviction of an aggravated felony after entering the United States
