Absolutely. It's a really good idea. I believe the proposal was also multiple-entry visitor visas that would extend for a period of at least ten years. I believe previous discussions have touched on the fact that it could be a way for parents and grandparents to be here while their applications for sponsorship are being processed. It's also true that not every parent or grandparent wants to come here to stay.
