what if i want to visit my son who is studying in the university?
Sir whenever you want to apply for a TRV for visit purposes, you will need to address the below points in your application:
1- Purpose of trip
2- Home ties
3- Financial circumstances
Each point will have set of questions to be addressed
1- The purpose should be consistent and make sense, you will need to address few sub-points. I will give you few examples:
Tourism:
Are you a regular tourist? when was your last touristic trip? what is your touristic travel history? Why only Canada? etc
Meeting a friend:
Already provided example in my last post
Meeting studying son:
Is your son full time student? since when your son is student (time spent of studying)? Does your son need your support? what will you achieve from meeting him? What will happen if you didnot meet him? etc
Medical treatment:
What is your condition? Why only Canada? what your doctor said? how did you choose to go for treatment in Canada? how did you find the particular Dr in canada? etc.
2- Home ties
What ties you have to home country?
Family? job/Business? asset/properties? job prospects in your country vs canada? ties family members in Canada vs family members in home country? etc
3. Financial circumstances:
Can you afford such a trip? from where the money is coming? how much money are you using out of your savings? does it make sense to spend that much money on a leisure trip? etc.
Example:
your trip is costing 4000CAD , you have 5000CAD in your account. Does it make sense that someone will exhaust 80% of hard earned monies on a leisure trip?
I gave you above example to set the right expection of VO from your application. Whenever you apply a application, the VO will be thinking in above mentioned points. If you dont address these points, you are likely to be refused. Reasons will be roaming around above mentioned points.
Good luck
