Unfortunately, the "four year degree rule" is an absolute requirement. I recommend a masters degree after the three year bachelors in your country for admission to a US or Canadian MBA program. 

Best of luck on your career 

 thank you very much for replying 

but what if i apply for a job and work for 2 yrs , will it be any help?

or should i go for a 1 yr graduate diploma from my home country i.e. India?
