I have my Interview this coming January and it says that I need to provide my previous passports, I dont have my old passports anymore since I didnt really expect to be applying for a K1 visa from then especialy since I was a minor. I moved from the Philippines at 2011 to Canada and we got new Canadian passports I believe after becoming permanent residents, then at 2019 we applied to be Canadian Citizens and I reapplied for the canadian passport at 2021, I havent seen my Philippine Passport since we even moved here and I dont really know if its actually required, we only ever flew to Japan and Canada and didnt even leave the airport with my Philippine passport I believe aswell as flew within inside the Philippines
