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.
Leechburg is a borough in southern Armstrong County, Pennsylvania, United States, 35 miles (56 km) northeast of Pittsburgh. Leechburg was founded by David Leech, for whom it was later named, and was incorporated as a borough in 1850. Located along the Kiskiminetas River, Leechburg was known as a major port of the Pennsylvania Canal. Early in the twentieth century, it had been the site of extensive steel sheet works, foundries, cement plants, and productive coal mines. Leechburg was the first place where natural gas was used for industrial purposes.
