How to Apply for aWork Permit in the U.S.
A work permit is an authorization from a country’s government that allows a non-citizen to work legally in that country. Applying for a U.S. work permit (also known as Employment Authorization Document or EAD) is a fairly simple process.
First, you will need to prove you are eligible by filling out a one-page form as well as attaching the fee, photos and other required documents. Next, you must submit it to the U.S. Citizenship and Immigration Services (USCIS).
Keep in mind that a work permit and a work visa are not the same and require two totally different application processes. Applying for a work visa to the United States, such as an H-1B, is a much more complicated process than obtaining a work permit.
