H4 without having H1 stamped (COS) on my passport

Hi,
I have H1 with COS (L1b) I dont have H1 stamped yet, my wife has h4 and now have to visit India, I wont be able to go with her. my question is-> Is there any problem if she doesnt have my passport with H1 stamped? I can give all pay stubs, letters, certificates etc. Can she go for H4 stamping with out my H1 stamping ?

regards,

I believe she can go. She should not have any issue as you have an approved H1.
