Thanks Dimitar, For answering my previous question, have one more question.

I have changed my employer in the last six months and i got I797A along with I94 attached to the I797A Document from INS when my H1 Case was approved. For the H4 Dependent Visa Stamping should my wife carry I797A original document?. Because I797 A is with my I94,since I797 A is an important documentation from INS which i should hold on to from my side, So what should i need to do, in this case. should i need to send the My Original I797 A to my wife for H4 Visa Stamping?.

Thanks
