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.
Middleburg is an unincorporated rural community with a post office sitting just off the Green River in central Casey County, Kentucky, United States. The first land owner in the area was Abraham Lincoln I, the grandfather of president Abraham Lincoln, who purchased 800 acres (3.2 km) in the area in 1784. In 1800, Lincoln transferred the land to Christopher Riffe. Riffe built a home there and operated a mill,which began the focal point of the community. He was also the community's first postmaster when the post office first opened on February 11, 1837. He named it possibly for Middleburg, Virginia; or because of its location midway between Liberty and Hustonville.
