In terms of where you can apply *and get admitted*, then you should either take a masters in management outside India, or take an MBA in the subcontinent. The FT MiM ranking includes both types of pre-experience programme.

Outside of India, MBA programs usually require at least two years of work experience. In fact, to get into an internationally-accredited MBA program, you'll probably need more in the range of three years of work experience, minimum.

Like Duncan mentioned, Masters in Management programs, which are usually designed for people with little to no work experience, might be a reasonable alternative for you, depending on your goals. Start with the FT's Master in Management ranking, which lists the best programs from around the world like EMLyon (France,) Cass (UK), Sydney (Australia), etc.

One thing is that there are no USA-based programs in this ranking. This is because these programs tend to be rarer in the US than elsewhere. However, there are some decent American masters in management programs (which aren't ranked) that you might look at: Duke - Fuqua has one, UMass Boston has several, Kellogg has one...

The Duke program has amazing outcomes for international students. More than 3 in 4 end up working in the USA.
