not sure if they send email . for regular mail it can take 2 weeks for the mail to cross border and arrive to US ( surprise, that' what happened with me) and I am sure they will take another couple of weeks to process it before mailing..
you can use trackitt.com to enter your case and track similar cases.
Hi All,
We applied under the new AINP scheme, without the pre-assesment. We sent it on Jan 15th. We have not yet received a mail saying that it has been received (do they send a mail?), tho my package status shows that it was delivered on Jan 16th. We are still yet to receive a file number too. How long does it take to get an email from them to say that our application has been received?
TIA.
