I previously worked in the US on an L1 visa, and was able to get an L2 visa for my wife (Chilean national) at the time. She never used it, lost her passport while the visa was valid, went to the US embassy to get a replacement... and they gave her a B2 visa, which I believe is good for 10 years.

I've since left the US, and now she would like to fly there in November to take advantage of the shopping around Thanksgiving as well as looking up some friends. I expect to meet up with her there (I'm from a visa-waiver country, so I expect no particular problems). The destination is one of the airports in the Bay Area (wherever I can find cheap tickets to ;-)

I'll try to make sure she has documentation indicating she plans to return home after the trip, not overstay, have enough money to support herself, etc. etc. She speaks reasonable English, though possibly not enough to handle a full-on trip-me-up immigration interrogation. She is not looking to stay in the US.

But I'd appreciate any pointers or information about whether the above plan is advisable, possible, or is there anything in particular to look out for?
