I do not know why you are not responding, but you are not charged per question, per response, nor per answer. So after I give you my answer, you can continue to ask me questions without additional charge until you are satisfied. I apologize if it is a site issue that you posted and the post did not go through.
If she used a B-2 to enter the U.S., she is on B-2 status and she cannot use an EAD granted through an H-4. She will need to leave the U.S., get H-4 stamping (if necessary), and come back into the U.S. using the H-4 visa stamp. OR, she can file an I-539 to change status from B-2 to H-4, but she MUST wait until the I-539 is approved before she could use the EAD that she has. Approval of the I-539 can take 3 or more months. I am truly sorry. I know this isn't the news that you want to hear, but I am trying to keep her from getting into trouble and I hope you appreciate that.
