The entire program may thus be completed in one academic year.

위와 같이 석사과정이 1년으로 되어 있는 경우가 있더라고요,

All courses and examinations must be completed within three years of the original registration. International students may be subject to additional restrictions imposed by the terms of their visas, as governed by the International Students & Scholars Office (ISSO)

근데 또 3년내에 끝내야 한다, 이렇게 되어 있는데요..

이런 경우 I20과 같은 비자관련 서류에 체류기간은 1년으로만 나오는건가요?
