Employment authorization a must to work in US.

The United States does not allow all visitors and immigrants to work in the United States. Only some types of immigrants as well as lawful permanent residents and citizens can work in the US. The restrictions on work maintain jobs for authorized workers, keep wages high, and ensure the safety of all workers in the US. Those who are in the US for a limited time but who are eligible to work need to file for an Employment Authorization Document (EAD). The EAD verifies the authorization to work and provides documentation that workers can show prospective employers; the EAD proves that an applicant is qualified to work in the US.
