You can always do a MBA. Now keep one thing in mind. The country of the MBA program is really not that important as much as the accreditation. These three accreditations are very important – AMBA, AACSB and EQUIS.
Which ever program you apply to, make sure it has at least one of these accreditations. Then you need not be worried about the programs recognition. Have a look at their websites and select programs listed there.

AACSB -
AMBA -…
EQUIS -…

All the best!
