I am hosting an exchange student from Brazil. He has a Study Permit valid for the next year, but it says "does not authorize re-entry". His Mother would like him to fly to the Dominican Republic to have a vacation with her next week. What does he need to do this?....ot will he be able to? Also in July he would like to go home to Brazil for the month and then return to Canada. I am so new to these things and don't know what to apply for or how to do it. Please help.
