Hi I applied my paper based file on November 2020. In background declaration form i miss one address which was in phillipines country. I was 15 years old when i went there and stayed there for 8 months but i forgot to put that address in my history because I can't remember the exact year . The stamps was on my opd passport and I renewed my passport.What should i do now? Should i let cic know or no because it was before my 18th birthday.
