Even if you have lawful immigration status (for example, current visa, entered the country with permission, etc.), if ICE believes that you could be deported from the U.S., they might issue a detainer against you when you are fingerprinted by law enforcement.
Certain criminal convictions could cause you to lose your current immigration status or prevent a permanent resident from renewing their green card. An arrest or conviction could also prevent you from changing your immigration status in the future, including becoming a U.S. citizen. Finally, an arrest, conviction, or order of protection could complicate your reentry into the U.S. after traveling outside the country. In each of these situations, ICE could start immigration court proceedings to try to deport you. Speak to your lawyer about how your criminal case could cause any possible changes to your immigration status.
If you recently became a U.S. citizen or were in the process of becoming one at the time of your arrest, it is important to tell your lawyer. You could still face consequences such as losing your citizenship, detention, or even deportation if you are convicted based on conduct from before you became a U.S. citizen.
