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.
Calumet is an unincorporated community in Mount Pleasant Township, Westmoreland County, Pennsylvania, United States. Although the United States Census Bureau includes it in a census-designated place with the nearby community of Norvelt, they are in reality two very different communities, each reflecting a different chapter in how the Great Depression affected rural Pennsylvanians. Calumet was a typical "patch town", built by a single company to house coal miners as cheaply as possible. The closing of the Calumet mine during the Great Depression caused enormous hardship in an era when unemployment compensation and welfare payments were non-existent. On the other hand, Norvelt was created during the depression by the US federal government as a model community, intended to increase the standard of living of laid-off coal miners.
