we submitted a pr application, the docs has already arrived, but we didn't receive any thing from cic. However we found that we made a mistake on schedule A( form 5669) that we unintendially missed the information about the refusal of US visitor visa of me ( the spouse, my husband is main applicant). What do you think what we should do? Write a letter to explain to cic, submit a form again or withdraw the application and submit all the docs again? Thanks advance for advices
