I don’t know what is AIP but I got an email on December 12:
This letter refers to your application for permanent residence in Canada under the Protected Persons class.
It has been determined that you meet the eligibility requirements to apply for permanent residence as a Protected Person. Please note that a final decision will not be made until all remaining requirements for becoming a permanent resident have been met. These requirements include medical, security and background checks for you and, if applicable, your family members. You cannot become a permanent resident until you and all your family members have met these requirements. Does it mean AIP ??
