Canada Visa

No chance at all. First, know where you will get admission to apply for visa. You need not try. You can try admission in New Zealand or UK; you will get it.

You have the required IELTS score and scored 77%, you will get admission. You may not get the free education because for that, they require 80%. As you have done MCA instead of doing MS in Computer Science, it is better you do some specialisation in the computer field when you do your Master's degree. It will make you more employable.

If you are going for Diploma course, it is okay. If you are going for a degree programme, you should have overall 6.5 and each component minimum 6 band.

Yes. Contact Embassy for details on these subjects. It may take quite sometime to get Visa. You should apply at the earliest for it.

You need to have no backlogs and 6.5 in all modules of IELTS. That's the basic requirement.

The reason for the gap, if you have gained some work experience in a particular field then you can mention that. Paperwork is of utmost importance to get a study visa.

Hi Jaspreet Singh,
Without 55%, you cannot apply. Even if you apply some low ranking college might accept you but you won't get a visa. So I will suggest you to omit your Canada college plan and venture out somewhere else. Also before applying anywhere check with the colleges directly as to acceptance of distance education.

Well, you will need to check if your credentials are valid in Australia or not.

Hello Sohanit, Student Visa is normally granted by Canada to a student who has obtained admission in an institute in Canada for studies. So don't worry. If you get admission you are bound to get Visa.

It is completely dependent on the schools you are applying for. You have chances to get your visa. IELTS 6.0 to 6.5 is a good score.
All the best.
