Supervisa is a type of visitor visa only. They give you multiple entry visitor visa. I am putting "visitor visa" as option.Then in this case, for super visa holders currently in Canada, Will we mark as other as super visa option is not there and then in comments mention super visa. Doubt on putting as visitor, because 1st thought that comes seeing the visitor is 6mnths validity and but they have stayed more than 6 months on super visa.
What are you putting in "To" dates if the parents are currently in Canada on super visa and don't know how long they are gonna stay?
