If you entered the United States without a visa or violated the terms of your visa, the U.S. may initiate removal proceedings against you. The removal proceeding is initiated once the U.S. government files the charging document, called; Notice To Apprer, with the immigration court that has jurisdiction over the alien. However, you may be eligible for a defense, which could stop the U.S. government from removing you. For instance, you might be a U.S. citizen at birth, married to a U.S. citizen, a victim of a crime, or was/will be harmed if he/she returns to the home country.
If you have been charged with a crime such as assault, domestic violence, driving while intoxicated, theft, fraud, aggravated felony…..etc, you must speak to an experienced immigration attorney and get him/her involved as soon as possible.
