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.
Allison is an unincorporated community in northeastern Wheeler County, Texas, United States, at the junction of Texas Farm roads 1046 and 277. Founded in 1929 as a stop for the Panhandle and Santa Fe Railway, the town was named for the general manager of the railroad, R. H. Allison. The Lone Star Townsite Company laid out the town. The town reached its height in population in 1941, just before the country entered World War II, at 200. It had a population of approximately 135 in 2000. During the 1970s Allison and the surrounding area benefited from the natural gas and oil development in the Panhandle-Hugoton field, the largest-volume gas field in the United States, and the world’s largest known source of helium. Between 1973 and 1993 the field produced over eight trillion cubic feet (230,000,000 m³) of gas. For years, the Allison Independent School District served the community's students. In 2003, however, the district merged with the neighboring Fort Elliott Consolidated Independent School District. The elevation for Allision is 2605 feet (794 m), and the town is located at 35°36′21″N 100°06′02″W / 35.60583°N 100.10056°W / 35.60583; -100.10056 (35.6058803, -100.1006736).
