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.
Harrisburg is a city and township in Saline County, Illinois, United States. The estimated 2007 population was 9,638, with a township population of 11,658. It is the county seat of Saline County. At the concurrency of U.S. Route 45, Illinois Route 13, Illinois Route 145, and Illinois Route 34, Harrisburg is known as the "Gateway to the Shawnee National Forest", and was made infamous for the Ohio River flood of 1937, the old Crenshaw House (also known as the Old Slave House), and prohibition era gangster Charlie Birger. A Cairo and Vincennes Railroad boomtown, the city was one of the leading bituminous coal mining distribution hubs of the American Midwest between 1900 and 1937. At its peak, Harrisburg had a population that reached 16,000 by the early 1930s, and had one of the largest downtown districts in Southern Illinois, but it has been in severe economic decline due to the decreased demand for high sulfur coal, the removal of the New York Central railroad, and several floods leaving much area around the city unfit for residential, commercial, or industrial use. Harrisburg is included in the Illinois-Indiana-Kentucky Tri-State Area and is the principal city in the Harrisburg Micropolitan Statistical Area with a combined population of 26,733.
