Most people arrested by Immigration do not face criminal charges. They usually go through removal proceedings (deportation). A removal hearing is very serious—an immigration judge will decide whether you can stay in the U.S. If you lose, you will probably be deported.
You do not have a right to have a government-appointed lawyer speak for you at a removal hearing. If you want a lawyer, you or your family must find one. When you are arrested, you should ask for a list of free or low-cost lawyers.
If you are put in prison, you may have to stay there until the removal hearing is completed. Sometimes you can get out if you promise to return. Or they may let you out if someone pays a bond. The amount of the bond varies. The minimum is $1,500.
Ask a friend or relative who is a U.S. citizen or has legal immigration status to pay the bond.
