if u want to do accounting, go accounting. Never heard of an IS graduate end up doing accounting. If you don't care what you would do but want to work in US (or care salary), go mism. it is not a difficult choice at all.
My personal opinion: I'm truly not sure why some engineer/science background people want to do accounting instead of IT. If you prefer finance, i can say finance can give you more money and potential. If you prefer marketing, it is at least more fun (more communication). Why accounting? Shitty salary and boring life. The only good thing is you have slightly better chance land a good MBA offer after couple of years and break into I-Banking. But that's also a very very tough path. Sorry for the offense.
