We are Permanent residents of Canada since December 2013.Last September we had applied for trv for our 5 months old daughter born in India and it got approved. Me and my daughter are planning to travel to Canada next month.I wish that my parents also could accompany us as their presence would be a great help for me when I return to work with a small baby at home.My question is whether it is possible to invite my parents also now.We own a house in Canada and our parents can stay there. My parents would be supporting themselves during the stay and they will be paying for their trip too. Is it possible to give another invitation letter in this small time gap (as we had just invited our daughter 4 months before).If it's possible ; what reason should they mention as their purpose of visit? Can they say that they are coming to help me to get settled with the kid and also to visit our home that we bought in Canada.
