It’s “normal” but not the usual. I’ve been waiting for my invite since Nov 2.
GCMS notes say everything is good, just waiting for oath.
Called IRCC 3 times and all 3 were met with a tired agent being like “your file is ok, on oath queue” and a “just be patient and contact your MP after 17 months”
Tried emailing my processing office’s oath scheduling email (twice) and they didn’t get back to me.
