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.
Trexlertown (also Trexlerstown) is an unincorporated community in Upper Macungie Township, Pennsylvania, United States. It lies in the Lehigh Valley between Breinigsville and Wescosville. Air Products & Chemicals is located adjacent to Trexlertown. The town also is the home of the Lehigh Valley Velodrome. Jeremiah Trexler obtained land adjoining that of his father in Upper Macungie Township, Bucks County, Pennsylvania, where he kept a tavern as early as in 1732. In 1734 a road was laid out from his tavern through North Wales in now Montgomery County to Philadelphia. As was the custom of the time, a village grew around the tavern, which came to be known as Trexlertown. -- 16:03, 12 March 2010 (UTC)
