The H1B visa, also known as a US work visa, is a nonimmigrant, employment-based visa that is granted to an eligible temporary worker. In order to be eligible, you must receive a job offer from a US employer and show proof that you have a bachelor’s degree or equivalent education in the occupation’s field. For an H1B visa, your employer files a petition on your behalf to start the process. Holding an H1B visa also allows you to apply for a green card.
