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.
The Dalles is the largest city and county seat of Wasco County, Oregon, United States. The name of the city comes from the French word dalle (meaning either "sluice" or "flagstone" and referring to the columnar basalt rocks carved by the river), what the French-Canadian employees of the North West Company called the now-inundated rapids of the Columbia River between the present-day city and Celilo Falls. The population was 12,156 at the 2000 census and was estimated at 12,520 in 2006. Also in the same area was the Petite Dalles or Little Dalles, or Short Narrows, which is now also inundated.
