Alien employees

In the United States, the term Alien employees refers to workers who take employment positions in American businesses but who are not legal citizens of the United States. Those employees who enter the country and obtain employment legally do so by securing employment visas. Employment visas are divided into two categories: immigrant visas and nonimmigrant visas. Immigrant visas are used by alien workers who are approved for permanent residency in America, while nonimmigrant visas provide for temporary stays in the United States for up to seven years.
