H4 And H4 renewal

I am on H4. Company A applied for my husband’s H1 transfer, H4 and H4 EAD. Husband never worked for company A.

Company B applied for H1 and my husband choose to go with company B. They also applied for my H4 before the original I94 expired.

Meanwhile my H4 and H4 EAD from Company A was approved. My question is should I apply for H4 EAD since my husband choose to give with Company B and my H4 EAD is based on company A?

H4 and EAD are not attached to any company. You can keep using the H4 and EAD as long as the primary H1B is in status and you have H4 and EAD validity.
