part-time MBA now vs. returning to India ?

Hi All,

I work in a global healthcare company in US and have about 7 years experience in R&D and Field Clinical. I recently got admits from UCLA Anderson (part-time), UC Berkeley Haas (part-time) and Wharton (exec) programs - however, I have long-term plans to go back to India/S Asia and I'm wondering if a US MBA makes sense right now. As if this was not enough to think about, there is a good position back in India with my company that I'm considering. If that works out, I'm hoping I can pursue my MBA from ISB/INSEAD (full-time or exec) in a couple of years having had exposure to emerging markets. Do you folks think the latter that is a better strategy than doing an MBA here and staying back for 4-5 years. Kindly provide your thoughts. Thanks.
