Question ： Do I need an Employment Authorization Document (EAD) while my I-485 is pending?
One who wishes to work legally in the United States must have valid work authorization. A person who files an I-485 generally may obtain an EAD, which confers work authorization. Such an individual must have the valid EAD in hand in order to use it to work legally. One who is in H1B or L-1 status may choose to use the H1B or L-1 to work in the U.S. in lieu of the EAD, even if s/he has a pending I-485. Individuals who do not plan to work do not need an EAD.
