Different names on Valid Visa(on old passport) and New Passport

[charansidhu5]

Hi All
My sister got a valid H-4 visa on her passport. She had to get the surname of her husband added to her passport so she got a new passport issued. Her old passport was cancelled(she still possess it though).

Now her Valid visa on cancelled passport has her name as Manraj Kaur but her new passport has Manraj kaur bhullar.

My question is will she face a problem at airports(Indian and US) due to that and if she will what should be procedure to get that corrected.

VFS-Jallandhar said that it is not required but VFS -DELHI said she will have to purchase a new HDFC receipt and schedule a new interview .Does that mean that its a new visa interview for her?

What are my options?
Can i go for correction or i have to get a new visa date? She has to travel on 1st so i will not have much time for scheduling visa interview.

Please reply urgently
Note: I know tshe has got a H-4 visa and this is Visitor visa forum but i believe that this is more of a general question spanning all kinds of visas,,,so please help

Thanks
Sidhu
