Thanks a lot Falcon....
But can you please suggest me how to migrate to Canada, as it is very urgent for me...and how much band score will be corresponding to 18 points in CIC self assesment test
Migrate to Canada is urgency need of all applicant who already applied and status is in-process, Medical done, RPRF req sent etc, but you still not applied I Guesss..!!! so, at my point of view there is no urgent required migrate to Canada for you at this level......!!!
try to clear IELTS with High Band in each Section (L: 7.5, rest of all R W S atleast re. 6.5 bands in each) you will get 16 points full.
if you still not awarded full 67 points then I suggest to get French language atleast clear some basic level Speaking and Listening you will get 2points atleast.
otherwise calculate points as you principle applicant or your spouse as principle applicant , if point will be 67 then apply you or your spouse as principle applicant. but remember keep in mind about NOC experience it should be match atleast 1 NOC work experience atleast for 1year within last 10years.
I hope it will help or you understand the process , if not please read CIC manual , google or this forum search option will help you.
