Canada

Hi Sanjay,
You can apply for a visa after you have received the admission offer from a university. 65% is a slightly difficult score to get into Canadian universities but you can check specific entry requirements on university websites. Apart from Canada try in Australia too. Remember you must also take the IELTS or TOEFL to meet English language requirements.

Hi Abhinav,
Some of the well-known universities are the University of Waterloo, University of Carleton, University of Alberta, University of British Columbia, University of Toronto, Carnegie Mellon University, UC Berkeley, UCLA, Cornell and so on.

GRE and TOEFL/IELTS are the essential ones.

You can check Thompson Rivers University and Vancouver Island University. Professional experience is not mandatory.

Hi Shyam,
Overall, the following provinces have good and faster provincial nomination programs:
Ontario
Saskatchewan
and New Foundland
For specific information on your area of interest you can check the Skilled Occupation List.

Hi Chirag,
What is ME? Can you confirm if its mechanical engineering?

I think you are asking which regions in Canada have the most digital marketing jobs, with the widest variety of business models. In that case, I think Toronto has to be tops. It has one of the most diverse array of industries in the world, being the 2nd largest cluster of companies in North America in about a dozen major sectors (telecom, banking, retail, pharma, tech, mobile, media, advertising, etc.).
All the best.

The 3 main reasons could be submission of incorrect information, your academics and finances. From 2009 onwards Canadian system is ok with dual intent, so intent of staying back in Canada is no longer that big an issue. However what it means is that you need to submit correct information, have a strong study plan and sufficient finances for the duration of your course

SPP program is available for mostly colleges (which offer applied degree's, diploma's and certificates) and a very small number of universities. If you want to do bachelors in engineering, you can do it directly from an SPP institution or non SPP institution. You haven't mentioned which level you want to study in Canada under SPP and for which level you are asking for your chances. It's difficult to give answers as you may get information which is not applicable to your situation.
