I dunno how long it would take.
but our mailing address was set as alberta and since our app was sent to mexico city april 5. we never received anything in the mail from them, no aor or police letter.
I dunno how they send it, but if they send it by regular post it could take 2 months. we have sent mail from bc to mex and it took 3 months regular post. But im assuming mexico city would send it registered... but than again im not sure lol.
If its possibly i would change the address to mexico, and send them a prepaid waybill.
like I said its been over 4 months now, and we just decided to change my spouses mailing address to mexico and give them a prepaid way bill because we still havent received anything and we are getting very impatient haha
