| Controlling Alien Admission - Applicability of Restrictions - Persons - Aliens Generally and Special Circumstances |
| |
| Immigration officials may exclude aliens who do not comply fully with applicable laws from the United States. Immigration laws are not aimed at U.S. nationals or citizens but instead focus on aliens and on those who cannot prove their claims to U.S. citizenship or nationality. Lawful permanent residents (LPRs) receive special consideration under immigration laws and are therefore discussed in a separate article. However, other aliens, including American Indians born in Canada, alien members of the U.S. Armed Forces, aliens in diplomatic and quasi-diplomatic positions, refugees who seek asylum, and aliens born in the U.S. without gaining U.S. citizenship may be subject to some or all of the country's immigration laws, as discussed below.More... |
