Those who wish to leave, are then threatened with disclosure to INS officials about the illegal work they have already engaged in, to force them to stay on the job. For example, agreeing to help provide child care services for a friend in return for a place to stay and spending money, can constitute illegal employment under the terms of U.S. law. INS arrests and deports a number of Czech citizens working illegally in the United States every year. Discovery and deportation have serious consequences for those caught working illegally. Illegal workers are first arrested by INS officials, and they may spend time in an American prison prior to deportation.
Deportees lose the right to travel for the United States for a minimum of five years.
This restriction is not waived, regardless of whether a future employer may require U.S. job training, study at an American university is desired, or if travel is needed for other emergency reasons. The names of deported foreign nationals are entered into Embassy and INS computer systems to ensure that further visas are not issued to those individuals. Following the five-year ban, future receipt of visa travel privileges would be subject to strict scrutiny by Consular officials, and applicants will have a difficult time overcoming the presumption that they will not again violate the terms of a tourist or other type of visa.
