I-94 Maiden to Married Last name change

[sree_uk2004]

Hello 

 

Please help me on the below issue:

 

My wife recently changed her Last name from Maiden to Married Last name in Indian passport. H4 I-797A and I-94 are issued before this last name change.

 

We went to CBP office for name change and they said this I-94 was issued by USCIS and CBP office don't do this correction.

 

Where should we get this name changed on I-94?

 

My wife is going to India next month. She is eligible for Drop box for Visa stamping.

 

Can she go for stamping with old Last name on I-797A?

 

Any help is greatly appreciated. I didn't find any article from recent posts.

 

Regards,

Sree
