Hello all. The applicant had a child over 20 years old on the application (inland sponsorship). At the time, the dependant qualified as a dependant even because they were under 22. The marital status of that dependant changed and CIC was updated. A letter was sent to them informing them of this. The child would no longer be a dependant. They are asking for a notarized letter and that the applicant should state that they are aware that they can never sponsor the child in the future... Which we kno that cos the child is now over 22. The child is not interested in immigration and had been listed as an "additional family member." Anybody with similar experience or even advice on how to approach this?' Thanks.
