Canada

IELTS score is not a big concern for visa officers, it is mainly the requirement of the university but you must have a strong hold in English and have a good profile otherwise they will reject your visa in any grounds they would want to.

Hi Lokesh,
Mention your academic grades and if you have taken IELTS etc.

Dear Aashish,
Although it is not necessary that u must have experience in country's local market, your +3 year of experience is enough to make your visa to go. Second thing is: If you are dedicated to work, struggler, have excellent performance during job then I don't think you will face any problem in finding Job abroad. There is plenty of options available specially in marketing field (because it is all pervasive).
And the third thing is I am suggesting you to go for Australia (most preferred) for MBA or UK (if not Australia then here) because Sydney school of business is one among the top 5 business school in world.

Hello Dinesh,
Of course you can do a certificate course in Canada. But what about jobs afterwards? Most countries are restricting entry to only high skilled jobs & surely skill acquired via certificate course could not be called highly skilled.
But you can spend money and do certificate course.

Hi Pallavi,
Directly after graduation, you can do PGDM not MBA since MBA programmes require work experience and you don't have it. Very few tier 2 colleges accept freshers for MBA courses.

It is interesting to hear that you need to do Diploma after B.Tech. It is better to take MS from Canada instead of Diploma.

$25,273 and $26,582 are some minimum costs for studying engineering (CS & IT) in Canada.
You can check the websites for fees details of different colleges at there.
