Hi there! I'm actually interested in anything you find out too. I currently live and work in Houston, TX but am considering a move to Queretaro as well. I studied in Queretaro for a summer in 2006 and spring 2007. There are some American families living in the city, primarily families brought there by businesses though. There's a newcomer club that seems really great in linking people up (if you search Newcomers club queretaro, I'm sure you will find it). I haven't met anyone in the club yet, but emailed someone about membership and they seem to do some neat things together. There are also a number of students who study in Queretaro from the US.

It's a really gorgeous city with all the modern amenities you could need.

The majority of the American retirees live closeby in San Miguel - so it depends on what you are looking for. If you're looking to live close to other ex-pats, that's the place. If you are looking to live with fewer ex-pats around, then choose Queretaro. Queretaro is also the larger, more modern and busy city of the two. Both are beautiful though.
