my boyfriend has dual citizenship in argentina and italy. he was born in argentina and it states that on his italian passport (i've never seen that on a passport before). he's coming to the US to visit me in december and even though he has a passport from a visa waiver country, i'm worried that they won't let him in because it says he was born in argentina. should i be worried? he hasn't been to the states before, he's only staying for 25 days and he will have sufficient funds. i don't see why they wouldn't let him in, but i could be wrong.
