Spouse's H1 to H4 Conversion with my H1 Extension

Hi all, My i140 has been approved and will be hitting H1B 6 year cap by January 2017.

Over 6 years H1B extension based on i140 will be filed by November 2016. My wife is in H1B and would like to covert to H4 EAD.

Can we file H4 conversion in parallel with my H1 Extension. Will H4 be approved when my H1 extension is approved or even earlier?

Should we wait for H1 extension to be approved before we can file H4 EAD ?

You can apply for H-1 extension and H-4 COS + EAD in parallel. All of them should be processed together.
