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.
Renfrew is a small unincorporated village on the Connoquenessing Creek in Penn Township, Butler County, Pennsylvania, United States. It was founded by David A. Renfrew in 1882 on his farm. Once a thriving oil town, only the Methodist church is still active. The general store and the gas station have long been closed. In September 2004, Renfrew experienced massive flooding due to rainfall caused by the remnants of Hurricane Ivan. The Buffalo and Pittsburgh Railroad runs materials to and from the AK Steel mill in Butler through Renfrew along Railroad St. Once used by the Baltimore and Ohio Railroad, it was at one time a thriving railway that would travel down to Pittsburgh.
