I am from Asia (Thaliand) and am thinking of going for my MBA in the USA. Considering I'm on a budget, I'm not looking at top schools, but those that are ranked lower. (Ohio State, the University of Minnesota, and Michigan State for example.)

Is it realistic to think that I'll be able to get a job in the USA after doing an MBA there? I have read horror stories about foreign students having to go back to their countries when they could not secure visas. How much of a concern is this??

You are wise to be concerned. Read http://www.find-mba.com/board/31921

Thanks for that link.

Are there specific schools that have better stats for placing international students? Is it that the top tier schools are just going to be better for placements, period?

Yes, I think you can look at the FT rankingshttp://rankings.ft.com/businessschoolrankings/global-mba-rankings-2012 and then add the scores for international mobility. With US schools, most of the mobility will be from the outside into the US. It looks like the top schools in the US are Thunderbird, Columbia and Wharton.

US job market is getting better but i would suggest you to consider UK and more specifically London which i believe is the best place on earth to live.

Both wages and costs are high in London. It's not worse than NYC ;-)

Visa are not so hard: if you earn over 30K, the visa is more or less assured.

Yes, it's quite like NYC.

But for an international student in London, you have to have a job offer by graduation. Otherwise, there are no options for a transition visa, like in the US with the optional practical training 12-month allotment.
