Wanted to update, application was for parents. Applied for visitors visa in April 2022. Was stuck in background check since August. They both have had Canadian visas, and has had and still has valid US visas. Should have been processed under CAN+. However it was not it seemingly due to time elapsed. Spoke with MP office, sent multiple webforms to ask for more info...all standard replies. Cant find any reason why the wait was for more than 1.5 years for a simple visit visa.. was constantly on the verge of retracting the application and apply anew...today shows as approved. Not sure yet how long the visa is valid for, single or multiple as of yet. The whole grueling process has made me emotionless and still grateful that it finally happened.
