Persons who have been convicted or charged with crimes after gaining resident status should be extremely careful in traveling. Certain crimes can render you inadmissible to the United States, and the government may be able to charge you with being subject to removal when you seek to return. This is the case even if they could not have sought to remove you if you had not traveled, or even if your conviction is extremely old. You could also be detained at the port of entry and held without the right to seek bond. It is extremely important that you have an experienced attorney to review your specific criminal records to ensure that they do not render you inadmissible to the United States.
