GaTech only permits OMSCS if you have a 4 year undergrad. In many countries undergrads are three years. Even you have a Master's, that is also not counted. 4 years undergrad or nothing.

Yup, in Europe I think almost every undergrad is either 3 years, or 3.5 if you are to get engineer title afterwards.

But then Masters is way more common to do afterwards compared to American system where it's rarity.

It is 4 years in Brazil. Sometimes 5.

There are 3 years non-BS degrees though.

My country only recently switched to 4-year undergrad for all streams. Previously, only Engineering had it (not counting professional degrees like Medicine, Accountancy, etc.)
