If you have been in the U.S. on the H1B visa and meet specific requirements, you can apply for an adjustment of status from H1B to green card. ... If you have filed an adjustment of status or immigration application (Form I-485), you can apply for an Employment Authorization Document (EAD).

Do you get an EAD card for H1B?

The EAD or Employment Authorization Document is given when someone has an immigrant application (I-485) pending. When someone is here working under a temporary employment visa such as the H1B, they don't need employment authorization as the H1B allows employment at a particular company.

Can I use H1B and EAD at the same time?

No, you can not work on both the H and EAD simultaneously.
