Immigration law determines whether a person is an alien, the rights, duties, and obligations associated with being an alien in the United States, and how aliens gain residence or citizenship within the United States. It also provides the means by which certain aliens can become legally naturalized citizens with full rights of citizenship. Immigration law serves as a gatekeeper for the border of the nation, determining who may enter, how long they may stay, and when they must leave. Immigration lawyers represent persons seeking temporary and permanent residency (green cards) status in the U.S., those interested in obtaining U.S. citizenship through a process called naturalization, and clients facing deportation and removal. Immigration attorneys may also represent businesses seeking to secure temporary visa status for foreign employees.
Pembina is a city in Pembina County, North Dakota in the United States. The population was 642 at the 2000 census. Pembina is the oldest community in the Dakotas. A fur-trading post was established on the site of present-day Pembina in 1797 and the first permanent settlement started in 1812. Until 1823, Pembina was thought to be in Canada, but in that year United States Army Major Stephen H. Long's survey of the 49th parallel revealed Pembina's location south of the Canada – United States border. The first post office in present-day North Dakota was established in Pembina in 1851. Pembina served as county seat from 1867 to 1911. Pembina is near the northern end of Interstate 29 at the Canada-United States border at Emerson, Manitoba. It is a significant crossing for road traffic headed to and from Winnipeg, Manitoba and is one of three 24-hour ports of entry in North Dakota. Pembina is home to the U.S. satellite plant of Motor Coach Industries, which completes assembly of intercity buses, for customers including Greyhound Lines.
