They should increase the time period and make it 4 years out of 10 years. 2 years out of 5 is very small amount of time. Essentially they are saying to PR not to study abroad. As most degrees are 3 to 4 years in length. Is some PR in Canada wants to go to Harvard for undergrad or Australia for good education, PhD etc, they are essentially penalizing that PR for improving their life and returning back to Canada to contribute to economy. And on the other hand they themselves are getting tons of students to come in and study. Sometime some study programs are not available in Canada and people need not be discouraged from seeking education outside.
