Canadian students on an F1 Students Visa Status are allowed to come into the United States no more than 30 days from the beginning of their program. In other words, they cannot come into the United States until 30 days from the first day of the start of their study. Early arrival may be important to allow students to settle into the states, clear their accommodation and be ready for their studies.
They are also allowed to stay in the United States for a period of not more than 60 days after the expiration of their program. Students who would like to stay beyond these 60 days must ensure that they renew their F1 Students Visa Status before the 60 days elapses.
