My wife has H4 stamped and it is valid till Jan 2019. Currently she is in India and will be travelling to US in Feb 2017(on H4 Visa). She doesn’t have Last name in passport and her name in the visa is printed as FNU Swathi Puttur Krishna. Now, I would like to reapply new passport for adding surname(last name) and want to put “Puttur” in the surname (taking middle word from current given name). So the final name in the passport is:
Given Name: Swathi Krishna
“Once we get the new passport (with the last name in the passport), do we need re-stamping with the updated name on the visa” Can she enter US with the old name on the visa?
