Canada

Dear Pranav, You may go to either countries as both are the places for your courses. If you are looking at Los Angeles or New York you would have more options to choose from in USA than in Canada. Both the counytries would be value for money & as Canadian dollar is almost 19 rupees lesser, I am sure would be a little more cost effective than USA.

Dear Shivam, You have to be academically sound in your high school ie. 9th to 12th for the same & apply for Bachelors in the major you want to pursue from Canada an year prior to the intake you wish to apply.
It needs an online application, LOR & essays in some universities along with an IELTS/TOEFL scores. If you may have SAT scores, that also helps.

What do you want to apply for, PGDip or Masters?

The validity of each degree is determined by the graduate office of the university you are seeking admission. Email the university ( admission coordinator of the chem engg dept.) with your details . They may ask for your syllabus.

Hi Pavan,
Both of these countries are popular among International students for mechanical engineering program.
You can consider following parameters to decide about the country.
cost of study
stay back period
ranking of universities
Placements
Location within a country
Hope this helps!
Best wishes,

Hi Anjali,
I would like to know which program are you planning to apply for. GRE is not mandatory in Canadian universities. Although it is going to enhance your admission chances if you plan to take it.
