Canada

Since you have one year stayback, I would say that you have a better chance of finding a job. How this actually works is that once you finish your course and apply for a job, they will first look at your Visa. If you have enough months to stay back, you have a better chance of getting the job. Of course, they look into your academics too. As for the second question, yes, once you get a job, your Visa will get extended as the company will provide you with a new Visa. All the best.

Different courses have different entry requirements. For an MBA most programs and universities require work experience. Also, many Canadian universities only accept a four year UG course. In your case you can look for PG Diploma programs. You can also check institutions like Thomson Rivers University and Vancouver Island University for MBA without work experience, many colleges like George Brown, Sheridan, Humber etc. Also, offer many pathways. You have to check through university websites and learn about the requirements yourself and then decide what to study.

Hello,
DDS is the same degree as BDS in India. It is better for you to do the Diploma first.

PG Diploma in Canada is not worth it, you can rather pursue it here itself in India, Canada is a great place for Studies of Masters.

With your great profile, you will surely get admission in a Canada university, But, a greater IELTS band will result in better University options.

First of all, you should take a degree from a university not a college. Keep searching for the courses in different universities. If you are not able to find in one university look for it in another one.

You cannot opt for PG without having a Bachelor's degree. Advance Diploma is not a Bachelor's degree. If you do have a UG degree prior to the Advance Diploma, you can then pursur your PG.
