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.
Columbia is a former California Gold Rush boom town that lives on as a state-preserved historic park and a National Historic Landmark that preserves the original, gold-rush-town flavor of the town, once dubbed the "Gem of the Southern Mines. " Founded in 1850 by Mexican gold miners, it is in Tuolumne County, California, United States. Although only about 2,000 people now live in this region near Sonora, California, at its height it was California's second-largest city. It was even considered briefly as a site for the state capitol of California. In 1854 the bulk of the town burned down and was re-built with brick and iron structures that survive to this day. Columbia's main street, part of the Columbia State Historic Park, is closed to automobile traffic but is open to horses and carriages, as well as pedestrians. The town, now technically a census-designated place (CDP), is located along State Route 49 just north of Sonora. The US Postal Service ZIP code for the community is 95310. Wired telephones in Columbia work out of the Sonora central office. Major points of interest in the area include Columbia Community College, a two-year, community college. Columbia Airport includes one 4,670-foot (1,420 m) runway and is busy with firefighting aircraft during summer. The annual Columbia Fire Muster here is often the earliest of California's summer musters.
