When hiring citizens of foreign countries, employers must ensure that those individuals have the proper visas authorizing them to work in the US.
There are several different types of visas depending on the individual's occupation, whether the individual is a student and whether the individual intends on coming to the US temporarily or permanently.
The requirements set forth by the US Citizenship and Immigration Services must be followed when sponsoring a foreign citizen for an employment-based visa. These requirements may differ depending on the type of visa.
