Is it still required to have Marriage Certificate for H1B/H4 stamping?

I have been married in Nov ’ 2011.

My wife applied passport few months back and received her passport , with spouse name stamped. But In my passport her name is not mentioned.

 

My wife is appling for H4 Visa, since My name is mentioned on her passport.

is it still required to have Marriage Certificate for H1B/H4 stamping ?

 

Thanks,

Marriage certificate is must for H4 visa stamping
