I have previously promised that I will submit a detail feed back once my mom got visa. Unfortunately I was busy up until now. I have gotten lots of request for sample invitation letter therefore I am attaching it below. My mom recently became widow and I am the only child so getting super visa was a very challenging. In her first attempt the Super Visa was rejected stating that she has strong ties in Canada. So I decided to hire an immigration lawyer as I was desperate to get her here and also wasn't aware of this forum at that time. The immigration law firm took my money without doing any work and dragged it for ever(I am in the process of trying to get my money back so I will write a detail review about this experience later).
Anyways, after going through this forum and reading all the posts related to super visa application, I was able to successfully submit the application by myself and bring my mom to Canada. A big thanks goes to Gary Goldshmidt from stone-hedgefinancialgroup. After reading his posts in this forum, I contacted him to see if he can provide any specific advise for my case and also to choose appropriate super visa medical insurance package for me. After hearing my story, he advised me to submit specific supporting documents and also told me it's better if I get a supporting letter from my MP. I think that advise made a big difference in my case. Different people may have different issues but getting a letter from MP was the biggest asset in my case. Even though Gary is a insurance broker/financial adviser, he has so much knowledge about immigration as he deals with different type of customers and have heard about many stories like mine. I called him multiple times with many doubts and questions and he always explained to me in details on what should be done. He didn't expect that he will spend his valuable time to provide free advise (nowadays nobody provides free advise. I paid consultation fee to my law firm but it was a joke as I have to tell them what should be done). I am not trying promote Gary here but when a person spend time with you and helps you out without any expectation, you will have to appreciate that.
I am a rookie and there are so many professional advisers in this forum who post lots of valuable information. Just go through them and read them all and submit a strong application which is hard to reject. Any supporting document or evidence you provide will just benefit you (even it may look stupid to you or others). I wish you all the best and if you have any question, you may msg me and I will get back to you at my earliest convenience.
Below list are some of the supporting documents recommended:
1) Asset info -> If he has a land / house under his/her name then provide the deed and certified valuation of the property.
2) Financial status-> Bank statement, pension, fixed deposit & etc
3) Job -> If he/she is currently working / doing any temporary work, then provide proof of that
4) Family -> Does he/she has any son or daughter? or any close family he is living with? Get letters from them stating why he need to be back?
5) Religious ties -> If he/she is member of any religious organization then provide letter or proof from church, temple, mosque & etc
6) Strong Invitation Letter from you stating why you are inviting him? How long he will stay? Why he will be going back? You may list his daily activities and his active life style or any hobbies / work that he enjoys there & etc
7) Letter from your Member of parliament specially if you got rejected in the past for a stupid reason (you have to take all your proof and ask them provide a supporting letter. If you get this letter...you have a very good chance).
8) Any other documents, facts or pictures (not necessary) to prove strong ties back home.
