An applicant realized after submitting their PR application that they'd forgotten to declare a previous US visitor visa refusal — and didn't yet have an application number. The thread was unanimous and urgent:
- Raise an IRCC webform immediately — don't wait. "Not a single query further" was the tone. You don't need your application number or AOR to submit a webform; do it now with whatever identifiers you have (UCI if known, full name, date of birth, date of submission).
- Submit it again after you receive your AOR. Members advised a second webform once the acknowledgement of receipt arrives, so the correction is firmly attached to the file under its application number.
- Include all the details. State the US refusal plainly: which visa, when it was refused, and the stated reason. The goal is that your file reads as fully transparent before an officer reviews it.
- Why this matters so much: the US and Canada share immigration information, so IRCC will very likely see the refusal regardless. A member reported a friend who got into trouble over exactly this omission. Declared-late-but-voluntarily is a correction; discovered-by-the-officer is potential misrepresentation, which can mean refusal and a 5-year ban.
