hello, i am planning to apply for a visit visa. my sister is a PR card holder of Canada. she has sent me a letter addressed to the immigration officer mentioning our relationship, purpose of visit, bank balance etc which I will submit along with my application. I have also prepared a cover letter from my side to the immigration officer. My question is, do I need another letter addressed to me by my sister inviting me to visit her? Or, the letter addressed to the immigration Officer from my sister suffficient?
You are planning to visit Canada as per the invitation of your sister. The invitation can be an e mail from her to you just inviting you being her beloved brother to visit her in Canada and spend some months with her. She could mention that you can stay with her and also she can mention some thing like shoulder your other expenses and will arrange a medical insurance... bla..bla..bla
A print of that e mail to you would be sufficient. You don't need to make another invitation.
