Dear Ketan. There are alot of good colleges in delhi offering more than one specialization in MBA on basis of MAT score. since you got brilliant mat score so you can easily get admission in any college which accepts mat score, but none of them Guarantee about foreign placements. and if you wana create your chance for working abroad you must have gone for CAT exam.
Well the preferred course is. MBA-IB.
good luck
