Hi, what if sponsoring parents but the sponsor has 2 dependent kids who are Canadian citizens so do we mention 4(principal applicant, PA spouse, sponsor, cosigner) or do we include 2 kids of sponsor as well. I tried almost 6-7 times but not able to link the application.
In your case, try with 3 or 4 and see if that works. Make sure you are entering all PA information correctly.
