Canada

You can apply for either of them. However, if you completed Diploma right after your SSC and if you don't mind to study further for four years, going for a Degree course would make better sense.

Dear Gaurav,
If you do a masters in Canada or Australia with a duration of 2 years then you get a post study work visa for 2 years and chances of PR are good in both countries, for Australia you would need to retake your IELTS and get 8 bands in all sections to get the required points for PR under the current system.

Hi Shahnawaz,
You may refer to Times Higher Education or QS Ranking for the top universities. You must select a college according to your profile and university requirements. Hence refer to the ranking charts firstly. Job opportunities are plenty but difficult for international students. You must excel in your academics, have good communication skills, previous work experience and so on. If you have the skills you will get a job. Hope this helps.

Hi Vivek,
For top universities, academic grades must be high( above 70%), IELTS requirement vary but 6.5 overall or higher is recommended. You must check individual university websites such as UBC, University of Toronto, McGill and York University for requirements. Hope this helps.
