Are work visas and a work permits the same thing?
Work visas and work permits are different authorizations. An alien who wants permission to enter the United States for work must obtain a work visa. There are many different types of non-immigrant visas for temporary work in the U.S. along with employment based immigrant visas for foreign nationals looking to live and work here permanently. A work permit authorizes people with visas to work in the United States. Aside from certain exceptions, everyone who is not a U.S. citizen or a lawful permanent resident (LPR) must apply for a work permit in order to work in the United States.
