Done & checked - with some of the Uni's I mentioned. They have replied 3 yrs education is fine for International Students (Asia & Europe).
Stanford's website :
Undergraduate Degree : The equivalent of a US bachelor's degree is required. Degrees from international universities offering only 3-year baccalaureate degrees are valid equivalents.
India: The two-year master’s degree following the three-year bachelor’s degree is preferred but not required.
Chicago's website :
Academic Record - All international applicants are required to hold a college or university degree equivalent to a four-year American baccalaureate degree. In light of the Bologna Accord, Chicago GSB will also accept all three-year international degrees to fulfill the undergraduate prerequisite for application to the GSB. You will be asked to either submit official academic records or provide a self-reported transcript
