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.
Embudo (also Embudo Station) is an unincorporated community in Rio Arriba County, New Mexico, United States. It is on NM State Road 68. The Embudo Station is located 2.9 miles south of the intersection of NM State Road 75, where the Embudo River flows into the Rio Grande. Embudo was founded in 1881 when the Denver and Rio Grande Western Railroad opened a station (depot) there on its Chili Line. The station was named after the village San Antonio de Embudo, located 2 miles up the Embudo River, and until 1902 both communities shared a post office and were known jointly as Embudo. In 1900, anticipating a separate post office in the village, San Antonio de Embudo changed its name to Dixon. When the Dixon post office opened in 1902, however, Embudo lost its post office. Embudo got a post office again in 1905 only to lose it in 1909. However, since 1914 Embudo has had its own post office, zip code 87531. Today, from the state road a concrete bridge, replacing the old wooden bridge, crosses the Rio Grande to the "Embudo Historic District" which consists of the old railway station and associated buildings. The United States Geological Survey (USGS) gauging station at Embudo, to measure the flow of the Rio Grande, was the first (USGS) stream gauging station and was established by John Wesley Powell in 1888. Embudo was also the first USGS training center for hydrographers.
