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.
Basin is a census-designated place (CDP) in Jefferson County, Montana, United States. It lies about 10 miles (16 km) southeast of the Continental Divide in a high narrow canyon along Interstate 15 about halfway between Butte and Helena. Basin Creek flows roughly north to south through Basin and enters the Boulder River on the settlement's south side. The population was 255 at the 2000 census. Archaeologists have discovered evidence of human habitation from 10,000 years ago at a site near Clancy, 20 miles (32 km) from Basin. From about 2000 BCE through the mid-19th century, nomadic tribes hunted bison in the grassy valleys that trend east, away from the Rocky Mountains and into the plains. By the time miners found gold in the streams in and near Basin, most of the these tribes of Indians had been forced onto reservations by the U.S. government. Basin rests above the Boulder Batholith, the host rock for many valuable mineral ores found in this part of Montana. After the town became a hub of gold and silver mining, Basin's population peaked at about 1,500 in first decade of the 20th century but gradually declined as the mines were depleted. Abandoned mining equipment, closed or barricaded mine portals, and the ruins of a smelter and ore concentrator remain in Basin in the 21st century. Historic buildings from Basin's heyday form much of the core of the CDP's small business district, which includes a fire station, a post office, two restaurants, a bar, a commercial gallery, small specialty shops, and the nonprofit Montana Artists Refuge. Basin has a small elementary school, its own water system, and a low-power radio station. Local volunteers and elected trustees provide limited services to the settlement, but it relies on the government of Jefferson County, Montana, for law enforcement and other services.
