If you've submitted a webform to add an extra document to your study permit application and haven't received the automated acknowledgment yet:
- Expect the automated confirmation to take longer than a couple of weeks. Members in this thread reported waiting anywhere from about a month up to 40 days before getting the automated response.
- Don't assume something is wrong just because IRCC's phone line is unreachable. Their contact number being hard to get through on is common and isn't itself a sign your webform failed.
- Avoid submitting duplicate webforms for the same document while waiting — this can create confusion in your file rather than speeding things up.
If it's been well over a month with no acknowledgment at all, that's the point to try IRCC's web form status inquiry again rather than earlier.
