I sent an email to IRB 2 months ago and quoted this page that you included in your reply.
Specifically, I quoted this sentence:
"In cases where confirmation of security screening remains pending at twelve (12) months from the date of referral, the RPD will convene a conference with the claimant, counsel and Minister's counsel and may fix a date for a hearing."
It clearly says that IRB can - at their sole discretion of course - do something if there is a delay beyond 12 months to receive FESS.
I understand that there is an unprecedented high volume of refugee claims. I appreciate all the efforts made by IRCC, IRB, CBSA and all Canadian government agencies. The separation is taking its toll on me and my family
