Asylum
Immigration relief granted to bona fide refugees. This relief is wholly within the discretion of the Attorney General. See definition of “refugee.”
Citizenship and Immigration Services (USCIS)
Part of the Department of Homeland Security. The primary focus of USCIS is administering immigration benefits and services. Similar to customer service. This is where Family and employment petitions, citizenship applications, and VAWA applications are sent.
Crime of Moral Turpitude
What exactly constitutes a crime of moral turpitude, we’re not exactly sure. CMT is not defined in the statutes. This is why you should contact an attorney. Attorneys will resort to researching the case law. What we do know is that some sort of “evil intent” must be an essential element of the crime.
If an alien is convicted, admits to having committed, or admits to attempting a crime of moral turpitude, s/he is inadmissible. See definition of inadmissibility.
Customs and Border Protection (CBP)
Part of the Department of Homeland Security, the CBP is responsible for guarding U.S. ports of entry. They inspect all who enter the US lawfully and enforce customs laws.

EWI
Pronunciation: \ee-whee\. n.
A person who entered without inspection. This is the proper legal term for “illegal immigrant.”

There is no quota limit for immediate relatives’ entry into the U.S. Therefore, immediate relatives have the highest priority among family immigrants and may enter the U.S. almost immediately after approval of their petition.
Immigrant
Immigrant is the legal term of art used by U.S. immigration law to refer to people who intend to live permanently in the U.S. and abandon their foreign residence. Anyone applying for a visa (whether permanent or temporary) is presumed to have “immigrant intent.” An immigrant visa grants a person lawful permanent residence.
