Thanks for your reply,
Actually most of people are saying that you will not be given admission in any college in Canada dye to study gape and age
My age 42
I completed my 2 years graduation in 2023 it was started in 2016 but I couldn't clear 2 papers and I gave those 2 papers in 2023 and I have cleared.
So I afraid that if the college will not give me admission so what will be happened.
My brother is in Canada he can invite me on visit visa. So I guess I should go through visit visa and get admission in college and start my study.
You need to find a school that will give you admission for a program. Once you have admission, you apply for a study permit. You cannot start studying without a permit. Your program must expand on your education and current career. Given your age, a masters is the best course, if you are eligible. You need to show ties to home country (job that shows higher pay), funds etc. Being in Canada when you apply will weaken your ties.
Not sure your plans, but studying is no guarantee that you will remain in Canada after your studies and work. Your age works against you.
You still need to be approved for a visitor visa too. You need to show your own funds, ties to home country (spouse, child, job letter with approved leave), travel history etc.
