Non-citizens who have violated U.S. immigration laws are often barred from subsequent U.S. immigration benefits. Being physically present in the U.S. without lawful status, entering the U.S. without inspection, having an order of removal, working without employment authorization, or having been previously deported will often trigger such immigration bars. Certain immigrations bars may be overcome with one or more waivers. Most waivers require that the applicant have a qualifying U.S. citizen or lawful permanent resident family member in the United States, and documentary evidence that such family member would suffer from hardship without the presence of the applicant.
