Answer: A non-citizen can obtain work authorization in the United States in various ways. For example, a legal permanent resident can legally work in the United States and they will have a document called a work authorization that simply states they’re authorized to work in the U.S. There are also many employment-based visas, which specifically are there to allow people to obtain work in the United States. There are some visas that are very specific: for example, an international company that has offices in the United States can apply for certain of their employees to work in the United States. And there is an application that you can file, and it is dependent on your status at the time and the reason for your filing, whether you will be eligible to obtain that work authorization.
