Applying H4 EAD with AC21 Rule

[Loganandh]

Hi,

I'm looking to apply for H4 EAD for my wife. My I140 is pending for approval. However, my H1B approval got extended beyond 6 year period using the AC21 rule. My PERM and I140 was applied 365 days before 6 year period. Should I go ahead and apply for H4 EAD ? FYI, I'm on my 5th year in H1B.

Regards,
