Hi @Faruk, I composed at article to guide you on this. You can read it here.
Here is a quick summary of the process:-
1. Decide on a program you want to study, then apply to a post-secondary institution in Canada. It could be a college or a university. The school has to be a Designated Learning Institution (DLI), accredited by a provincial and territory government in Canada to host international students. Check out the list of DLI's in Canada here.
2. After you apply to a DLI, the school will send you an acceptance letter if they decide to admits you as a student. This letter will be needed to apply for a study permit.
3. Now that you've been accepted by a designated learning institution in Canada, next step is downloading the application package if you are applying on paper, or sign upfor a IRCC secure account if you are applying online. You will have to complete and submit your application at a VAC (Visa application centre) in your country if you are applying on paper or if you wish to apply online, you must make sure you have access to a scanner or camera to create electronic copies of your documents to upload, and a valid credit card to pay your visa application fee.
4. Start gathering supporting documents that will be submitted along with your study permit application. This documents must show your proof of acceptance, identity and financial support. In some cases, you might be asked to provide a Police Clearance Certificate (PCC), and in most cases a medical report may be requested.
5. After submitting your study permit application, you should find some free time to learn more about the country and read our article on traveling tips for international students while anticipating for the decision on your application. You can also check how long your application will be completed by checking the processing times.
Wish you all the best as you set out to begin your adventure of traveling to Canada as an international student.
