Surname Change while on H4

[shergillharinder]

I am in US on H1 and want to have my wifes surname changed to surname after marriage. I read that I will be required to apply at US consulate to get that done. Though I understand the process of getting it done, I am bit skeptical about - As they will issue a new passport, what wil happen to the existing H4 Visa Stamp on my wife's passport ? And Will it bring some trouble while going back to India , I-94 and other documents as the US guys will have the previous surname in their database.
Any help is appriciated.

unless it is absolutely imperative to change the name right now my apprach will be to wait till you need to get a new H4 stamp and get the passport changed before that. If you do get the new passport changed now, you will have to carry both passports and marriage certificate and also file for amended I-94
