You said you already have enough hours to sit for the CPA exam (150 hrs?), which means you will not be learning anything new if you do a Masters in Acct. Instead of getting a Masters it would pay you hugely if you focused your energy in getting a CPA. If you go to Nepal after getting a CPA you will be able to market yourself much better than with just a undergrad.

I would join maybe something like kaplan and start studying for the CPA. Take all four test and if you try it is really not that bad. Good luck!
