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.
Carville is an unincorporated community in Iberville Parish, Louisiana, United States that is 16 miles south of Baton Rouge on the Mississippi River. Carville is the hometown of political personality James Carville and was named after his grandfather, the postmaster. It is also the location of the National Hansen's Disease Museum, which records the history of the U.S. Public Health Service Hospital there, which for a hundred years treated leprosy (now called Hansen's Disease) patients. The hospital has been closed, but several of the buildings remain.
