Hello, an IELTS of 6.5 and above is recommended for PG level courses in Canada including MBA. However, it is advisable that you check the university's website for university specific requirements.

Hello, your study permit is enough for your co-op program and as an international student, you will be allowed to work alongside your studies. You will require a work permit after you graduate.

No, it won't as everyone has the right to travel.

You should write TOEFL and GRE to study abroad. You must go for the selection of the university/college, where it's offered well (your particular stream). Some colleges don't ask for your GRE score. So, you can only clear TOEFL with a score which university asks for.

Hello Anuranjan,
You have scored perhaps enough marks in your graduation exam and I feel you can get Admission in a Canadian college for MS. But then there are many more hurdles to cross and negotiate. It's best to take advise of an expert agency dealing in this routinely.

Hi,
Only a diploma or advanced diploma won't guarantee or help you find a high profile job. You may only end up as a very basic entry level worker. If you are looking for career growth you have to aim for higher qualification like Masters or PG Diplomas and not undergraduate diplomas.

Hi,
You may obtain visa provided you have been offered admission in a college and have a very good career planning. You have to explain the same to the visa officers. Ask yourself questions like why management? What do you want to do after gaining the management degree?
It will depend on your application profile and how you project your needs.
