Wow, that is hard. Not many schools start in the spring. There's a good list of top schools' starting times at Which schools start when http://www.find-mba.com/board/41131 but with his GMAT score he will struggle. Most of the schools that start in the Spring are outside the US, like EDHEC and the Australian schools.

I can't think of a single school offering a traditional, full-time MBA program starting in January in the US at which somebody with a 610 GMAT score would be competitive.. Columbia has its J-term start, but there's no way he's getting in with that GMAT score.

Your only real option is to look into flexible, regionally-facing MBA programs that target working professionals. These are not for everyone, especially if you need a student visa, but you can often load up on classes and finish relatively quickly, so there's that. And many have several different start points throughout the year.

Something like CSU Northridge, for example, might work. UMass Amherst's part-time/online program or Ohio University's Professional MBA program, as well. You'd have to do some research yourself, depending on where you would want to be and what you're looking for.

I agree with you..
