I'm currently on an O-A Visa that I obtained in Canada. My visa will expire on Aug 21, 2024, next month. However, my insurance will expire Aug 2, 2024. My stamp says I must leave on Aug 2. Understood. However, my question is this. Can I obtain insurance for those extra 19 days and then depart on Aug 21, 2024? It just works better with my plans. I don't think it's possible, but I wanted to ask. Thank you.
