Many people want to come to the United States to work. To work in the United States, you must have one of the following:
-A Permanent Resident Card (also known as a Green Card),
-An Employment Authorization Document (work permit), or
-An employment-related visa which allows you to work for a particular employer.
Each of the documents listed above has different application requirements. To apply for one of the documents above, you must meet different requirements.
If your application is approved, the conditions you must meet and how long you can work in the United States will depend on whether you receive a Green Card, work permit, or visa. It is important that you adhere to all the conditions of your particular work authorization. If you violate any of the conditions, you could be removed from or denied reentry into the United States.
