I visited US last year on a B1 visa, came back and got a new passport made as I added a surname (old passport had first name unknown/FNU).
I am planning to apply under L1B blanket through my company with new passport and have a few doubts:
Do I carry both my new and old passports to consulate?
Do you suspect any problems arising out of the fact that I have changed my name?
Is my B1 stamped on old passport that stands cancelled now, still valid?
Thanks in advance!
