But majority of the business schools there require 4 year education background and I have only 15 years.

Do you have an undergraduate degree?

It seems that you have 3 year under graduate degree.The first thing is it must be a regular degree from a college affiliated to an accredited University. Few universities even accept 3 year degrees.Just check FAQs if u visit any college website.
The best thing to do to overcome 4 year degree condition is to go for Masters.That is the best thing to do.
If u have completed Bachelor of Commerce,go for Master of Commerce (M.com) this must be sufficient.
If u intend to pursue accounting courses like CPA, M.com will give u 150 credits which is required for the eligibility.
Go for Masters.It is always safe. there is also a possibility to get u r visa rejected if certain prerequisites are not satisfied.

Siddharth,

You have lower work experience than most candidates, therefore I think you can consider doing a master's program. We had helped one of our applicants with 15 years education apply to some b-schools last year. Some programs that accept 3 years education are- Foster, Carlson, BYU- Mariott, Mason (and some more)

Some of the top programs like Wharton, Booth, Tuck, Darden, Stern also accept 15 years of education, but considering your low work experience, I would expect you to make a realistic judgment about where you want to apply.
