Wives H4 stamping when my H1 stamping is under 221g process

I recently got married and submitted the DS160 for H4 stamping for my wife and then I went for stamping first. Unfortunately I got a 221g blue slip requesting for more documents. Is it still ok for my wife to go for H4 stamping when my H1 stamping is under 221g process? thanks in advance.

I would delay her stamping until your 221g is cleared. If not, her stamping may also result in 221g until yours is cleared.
