@ericvu39 , assuming you continue to meet the requirements of the visa ( F-1 , ), you are still exempt without regard to EAD. However , you mention I-485 -- is your family / employer sponsoring a status change for you ? If so till that has been resolved you still retain then F-1 -- No?
On looking over I don't know if I have fully answered your question or not ---- perhaps I am missing the point you are making--- please can you elucidate ?
