INADMISSIBILITY
US immigration law prohibits the issuance of a visa and admission to the US to any person who is ineligible for a visa and admission under US law. Grounds of inadmissibility, listed in the Immigration and Nationality Act, include persons convicted of a crime involving moral turpitude (with certain exceptions), controlled substance violators, and persons who by fraud or willful misrepresentation of a material fact, seek to procure (or have sought to procure or have procured) a visa, admission to the US, other documentation, or benefit provided under the Immigration Act. Most applicants for a nonimmigrant visa who a US consular officer finds ineligible may apply for a waiver of inadmissibility.
