Hi i have overstayed in us for almost 10 years (age from 15 to 25) to be honest, i didnt know that i overstayed till age of 23. Now im back to my home country and served military service for two years and want to go canada with legitimate visa this time. I already got fbi background report clean. And considering if i ever mention about overstayed period in us, becasue study permit application doesn’t exactly ask about it, only place i can think of is mention at the letter of explaination. But to be exact, its not really a letter of confession, its your explanation of your study plan in canada. Should i just apply and see how cic responds ? Or just reveal everything on the explanation letter?
