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.
North Chelmsford is an unincorporated village in the town of Chelmsford, Massachusetts, United States. Although North Chelmsford has its own zip code, library, post office, police station, fire station, and local calling area, it is run by the same local town government and is part of the same school district as Chelmsford. North Chelmsford is more industrial, more densely populated, and generally less affluent than the rest of Chelmsford. North Chelmsford's separate identity and the town government's perceived bias one way or the other is a political issue - the Lowell Sun ran an article on August 7, 2005 describing the situation as "Chelmsford's Civil War Still Raging On. " Bumper stickers such as "I'm from North Chelmsford - Don't Tread On Me" can be seen around town. When it comes to Chelmsford's rivalry with neighboring Billerica though, Chelmsford and North Chelmsford stand firmly united.
