I sent the request to get the letter on an evening and got an answer the following morning, didn't take that long. I got the certificate in Mexico City and was sent to a different office to get my fingerprints done, so make sure you guys go early to get it done in one day in case you have to do the same. It took about 8 business days to process. She will have to pick them up or leave a notarized letter to have somebody else pick them up. Might be better if she waits until she has them in her hand before she leaves, just in case something goes wrong.Anyone knows how long it takes to get the official request letter from MXICO-IM-RAU@international.gc.ca to get the police certificate? My wife is scheduled to travel out of Mexico soon and she's ready to go get it done, but still waiting for the letter.
