I recently graduated Master degree program which commonly takes 2 years, but usually students complete their program 20~22 months because we don't take spring and summer semesters in the final year. But the thing is that my transcript and letter of completion do not mention about length of my degree program, but my actual start and end of course which is only 22 months time span. Do I need to prove official program length through some other document? or CIC officer just consider all master degree program 2 years long and would issue us 3-year PGWP?
