I am a new permanent US resident (Green Card) with a good USA credit score (around 7), under a US security number. I owe $22K as a personal loan to a Canadian bank (under a Canadian security number). I am still a Canadian citizen but I will never move back. I will apply for my US citizenship in 5 years when I am allowed to do so.
I have been paying "interest only" for over 7 years and have never been late or behind in my payments. I don't think I will ever get to make this debt a priority with my money.
What would happen if I decide to stop paying the interest or declare bankruptcy on my Canadian SSN? Would it affect my US SSN and credit score?
Thanks for any input!
