Sent my application on Jan 27th, and ANIP received it on Jan 29th (Have no idea why it took two days for Canada Post to send one express mail from Edmonton to Edmonton
)
Got "rejection" with the entire application package back on March 1st since they asked me for the Pay Statement. However, since I applied under SRS Engineering Occupation which does not require a Pay Statement, they made a mistake. I resent my entire package along with an explanation letter, on March 2nd again.
Then I received my file number today (March 8th).
Oh sounds good. You got your file number anyway. Good luck for the further process.
