Dear Saurabh,
There are several good websites on MBA programs that should give you an idea of what programs offer a 1 year option. From there you can compare each program to your list of criteria to determine which are the best options for you. I also encourage you to read our sticky on school selection for other tips. There can be many differences between a 1 year and 2 year program beyond the duration. One year programs might not have as much elective coursework, they do not usually include the opportunity to do an internship, and many have prerequisite coursework in business. I think you should spend some time conducting research and thinking about what you are looking for from business school. Then you will know your criteria for schools and can come up with a target school list.
Good luck,
Lisa
