Hi guys,
the need for ielts depends on the situation.. for example.. i am from India.. I did not have to submit an IELTS because .. I did my schooling and graduation in english medium school and college.. and I also got a letter from my college saying the mode of education was in English, also I did my PG Dip in New Zealand and Masters in Australia, and I have letters from those institutes as well stating that the course was taught in english, so I did not require it. Therefore, it depends on how well you can prove the case officer how good you are at communicating in English, if you do not have proof in terms of work experience or education that you have used the english, they might request you for an IELTS or any other form of language test.. so depending on your situation .. do the needful accordingly.. hope this helps .. cheers
