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.
Leesburg is a historic town in, and county seat of, Loudoun County, Virginia, United States of America. Leesburg is located approximately 40 miles (64 km) west-northwest of Washington, D.C. along the base of the Catoctin Mountain and adjacent to the Potomac River. The town is also the northwestern terminus of the Dulles Greenway (a private toll road which connects to the Dulles Toll Road at Washington Dulles International Airport). Leesburg, like the rest of Loudoun, has undergone considerable growth and development over the last 30 years, transforming from a small, rural, piedmont town to a suburban bedroom community for commuters to the national capital. Current growth in the town and its immediate area to the east concentrates along the Dulles Greenway and State Route 7, which roughly parallels the Potomac River between Winchester to the west and Alexandria to the east. The Federal Aviation Administration's Washington Air Route Traffic Control Center is located in Leesburg.
