I was refused 4 times in my student visa application for Canada. Do I still have chances to be approved?

Please request your GCMS notes to know the proper justification behind the refusal decision taken by the visa officer. After you get the GCMS notes, go through each point carefully and try to understand why the visa officer rejected your application. Once you know the reasons, try to overcome each and every one of the problems and write a letter of explanation or a cover letter to addresss the concerns raised by the visa officer. Make him believe that your true intention to go to canada is only to study, and not to immigrate and you will leave canada once your study is done. Make sure to show legitimate money and legitimate properties. Make sure to show the visa officer that you have significant ties to your home country and significant property to inherit once you come back home. Make sure the subject you chose to study in canada is in relevance with the subject you studied recently and will benefit your carreer in the future. Mention these in the cover letter/letter of explanation. If everything is done correctly, by the will of the god, you will get your study permit.
