Hi,
For undergraduate programs, you will need German language proficiency but check the language of instruction on university websites. At least A2 level is required for most UG programs. You can also check this if it helps for your German language training:

Hi Harry Pruthi,
IELTS is an English language requirement. If you have so many years of gap, you better first check with the colleges directly. You have to justify your gap, mention what you did, and why you took the gap if you have gained work experience or so. There is no straight answer to your question, profiles are evaluated on a case by case basis and will depend accordingly.

You cannot even apply to Canada without IELTS. There is no question of getting a visa without IELTS. IELTS is to prove your English language proficiency. Without proper language skills, you will not be bale to complete your studies successfully.

Hello Ashish,
Where do you want to apply? Did you choose any university? Did you check the university specific admission requirements? I would like to mention that for a majority of the MS programmes, the IELTS requirement is 6.5. You have to check this with the university while applying. Your CGPA is also alright but not very competitive. So, carefully check all the requirements and apply.

Yes, you can apply with these grades. Make sure you get 6.5 band in all four modules in IELTS.

One basic requirement is to take the language proficiency test and you must have good grades in your previous degree. Oxford does not entertain any admission applications that are low in grades.

Most of the or almost all European countries ask for your language proficiency test. It is must these days.

After 12th, you need to take SAT in order to be eligible to apply to a lot of major universities abroad. However, it is not compulsory. Some colleges do not require SAT scores. Some require ACT. But some require none of them. I would suggest you take SAT preferably in 12th grade or even after that as soon as possible and then look into individual websites of the colleges you want to apply to. To check if they accept TOEFL or IELTS. Both of them are English tests. some colleges ask for TOEFL and some want IELTS scores. If you don't know how to get started, attend some study abroad fairs.

Yes, IELTS is a must to go to Canada. Overall, of 6.0 for under graduation and 6.5 for post-graduation is required.
