Hi, do I need to have a US visa for flag polling?I recommend people whose study permit is about expired to apply PGWP at border, I succeeded to get three years PGWP at rainbow bridge border recently, the staff there was very nice provided You must bring along all documents, official graduation letter and official transcript in sealed envelope, more than three years valid passport and still valid study permit. By the way, they only do flagpole on Tue, Wed and Thur, Good luck to all
