Applying for H4EAD standalone & transfer.

Hi,

We are applying for H4EAD standalone with current employer.

I have a chance to switch and apply H1 + H4 + H4EAD (Concurrently premium).

Question:

Should I apply for H4EAD twice?

OR

Should I skip either of them?

Will H4 transfer cause RFE/issues?

Thanks.
