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.
Levittown is a census-designated place (CDP) and suburban community in Bucks County, Pennsylvania, within the Philadelphia metropolitan area. The population was 53,966 at the 2000 census. It is 40 feet (12 m) above sea level. Though not a municipality, it is commonly recognized as the largest suburb of Philadelphia in Pennsylvania except for Upper Darby Township, (which is the largest suburban township in the three surrounding Pennsylvania counties). Other suburban townships in New Jersey boast larger populations, but these municipalities consist of more than one locality (both Camden and Cherry Hill are urban and suburban communities, respectively, just outside of Philadelphia that have more residents).
