year be counted as 16th year? I'm working with an MNC, and my education is of 15 years(10+2+3). For our business process, i may have to go to USA, but heard also that it requires 16 years of study to go to USA, is it true?

Also, I'm pursuing MCA, want to know, will the 1st year that is completed be counted as the 16th year of my study or i've to complete my MCA first.
