What do you want to do ultimately - work in the US/Europe?
Do the MM now and it puts you in a position to work in the US/Europe after graduation.
It sounds like you're looking at the MBA as some end game, and it's not. What is more important for your career than a degree (MM or MBA) is getting the kind of work experience that you want in finance. Whether you get an MBA or not isn't as important. You now have that chance to move to the US, so you should take that opportunity now, which will allow you to work in the US sooner than later.
