H4 EAD validity when H1 (primary) transfer happens

[vasudevadv]

My spouse had her H1 and i140 from Company A and due to that I got my H4 EAD. Recently, she accepted an FTE offer at Company B and got her H1 transferred.

Now, Company A would want to withdraw her i140 since she is no more associated with them. Company B has not filed for her i140 yet.

What happens to my H4 EAD status which i got based on Company A’s i140 application and if they withdraw it. My current H4 EAD is valid till June 2020.

Please advise.
