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.
Sullivan is a city that straddles the border of Franklin County and Crawford County in the U.S. state of Missouri. The population was 6,351 at the 2000 census. Stephen Sullivan founded the city in the late 1850s and cleared brush, which facilitated the building of the railway depot there, and the railroad named the town and station after him in 1860. In 1856, when a post office was established in present-day Sullivan, the local postmaster named the place "Mount Helicon". This short-lived name was after an actual mountain in Greece that was the mythical sanctuary of the Muses. Between 1920 to 1960 the city grew from 900 to more than 4,000 residents, making Sullivan the second-fastest growing city in the state during that time.
