I want to apply for Canadian student visa and also I want my mom to be there as a visitor during my student program. Our plan is that my mom applies for a 5-year multiple entry visa before I apply for a student visa. My family in Iran only includes my mom and me. My sister is in the US. and we don't have any other substantial tie other than title deeds in Iran. I was wondering if these visas would be accepted. Our concern is that getting visa for one reduces the chance of getting visa for the other because of lack of family ties in Iran. And also which application is better to be submitted first.
