In the United States, some aliens must have a U.S. Citizenship and Immigration Services-issued work permit (formally known as an employment authorization document or EAD card) before obtaining employment. Some states also require minors to obtain a school-issued work permit before getting a job. If you are an immigrant to the United States and unsure of whether you're legally allowed to work, consult with your immigration lawyers to learn whether you're legally allowed to work and if you need to obtain an EAD card. Work permit lawyers can also help teens who are seeking employment but are unable to obtain a state-issued work permit.
