Actually I am not inviting any one . We have applied for PR, today my husband got a mail from IRCC for additional documents. My daughter is under my full custody and she is with me and my present husband from the very first day when we landed in Canada. My husband is on Work Permit, and is the step-father of my daughter. So we are not sure why IRCC is asking for IMM5646 from us. Please share with us any information or suggestion regarding the issue.
