I received AIP letter first before I saw a DM change on the Sponsor side on Ecas and after 24 hours I saw a DM change on the Applicant side on Ecas. Apparently, it took 48 hours to get DM on both sides after receiving AIP. I received AIP via MyCIC account and SA via my spouse email, nothing was mailed to our mailing address.How long after seeing DM for sponsor on ECAS did it take to get the SA notification? We have DM on ECAS now for sponsor but nothing by email or regular mail to indicate formal SA. Curious if there is a lag time? Got AIP for PA last week.
