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.
East Greenbush is a town in Rensselaer County, New York, USA. The population was 15,560 at the 2000 census. The word Greenbush is derived from the Dutch "Groenen Bosch," referring to the pine woods that originally covered the land. The first settlement of the land now known as East Greenbush was made by tenants under Patroon Kiliaen van Rensselaer around 1630. The town was formed in 1855 as the town of Clinton, the name changing to East Greenbush three years later. It is mostly suburban along its major highways and rural in the southwestern and northeastern corners. Interstate 90 passes through the town. It contains the west (or south) end of US Route 4 and the northern terminus of NY Route 9J; as well as US Route 9 and US Route 20. The last two are concurrent, under the name Columbia Turnpike, and is often referred to by locals as "9 and 20".
