However, I am still concerned about the fact that a visa is no guarantee of entry into the US and it all depends on the customs interview. Given that she has a valid visa, a return ticket, and a gig (PhD program) in BA, is there anything I can or should do to help the situation? Write a letter of support or something? I've heard of such things, but I am not sure if they are mostly for the visa application process (which is already completed) or for the customs interview upon arrival in the US. and don't worry, the message is definitely received regarding NOT implying any romantic involvement. I have no trouble withholding information about my personal life from my government, since it really is non of their goddamn business!
There seems to be no shortage of strong opinions on this subject, and I certainly appreciate them, but I am especially interested in those of you who have personal experience or know actual stories about valid visa holding Argentinians who have visited the US. What kind of issues have they had and what do they recommend. I have already scoured US .gov websites on official policy and I am curious about actual practice.
The big problem is actually getting the visa. Since she has a valid multiple entry visa she will have no problems. You are worrying for nothing.
However she should under no circumstances say she is visiting a "boyfriend". Oh, & she should have money & credit cards on her.
