What country of application?
Did your parents have US or Schegen or Canada visas before?
I applied 7th May for parents from India, Biometrics done 17th May, No response yet.
From Iran and no, they didn't have any US, Schengen or Canada visas before. I emphasized that I'll take all the responsibility for their expenses and they'll go back. I showed mine and my husband proof of funds for them. The processing time for Iran is 110 but they got approved within 30 days.
You'll hear back from IRCC soon. I literally got no updates between submitting their application and their PPR. Even their biometrics got updated after they got the approval. So be patient, IRCC works in the mysterious ways lol
