depends on u actually, no matter where u are if u fail to live, u will still fail. i've met many ppl like ts, usually they're the one that are introvert. interviewing them shows that. (im not saying ts). sure, they can become dentist, engineers etc but if they still lack of competence, thats ur own problem.

furthermore, their policy on foreigner has been changed, HR's giving priority to locals in this recession. in USA alone, many ivy league grads struggling to get jobs.

just my 2cents, if u feel unsure, why dont u go there for 2-3 months and mix with them, so u'll sure what you should do.
