The United States’ immigration policy has several purposes and it focuses on renewing strict, out-of-date, and inefficient deportation policies. First of all, it provides family reunions by taking in immigrants who have family members that already lives in the United States. Secondly, it aims to accept workers with specific types of skills that can fill positions in professions that are assuming to be experiencing employment shortages. Thirdly, it seeks to provide
protection for people who may experience racial, political, or religious persecution in their home country. Finally, it seeks to establish diversity by providing admission to people from countries that historically has low rates of people immigrating to the United States. There have been established multiple categories of permanent and temporary admission to achieve those wide-ranging goals.
U.S. policy provides two particular paths for the lawful admission of noncitizens: permanent admission or temporary admission. In the first category, the noncitizens may be granted permanent admission by being given the status of lawful permanent residents or LPRs. Noncitizens that get admitted in such a capacity are formally classified as immigrants and they receive a permanent resident card, which is also referred to as a green card. Lawful permanent residents are eligible to work in the United States and they can later apply for a U.S. citizenship.
