I will be the prinicple applicant for EE but I want to immigrate with my wife.While I can get her IELTS score( which will fairly less) I dont want to get her ECA done. If I happen to score above 440 alone, is it still mandatory for my wife to get eca and ielts done.If i get her ielts score say in the CL4 or 5 can it affect my score?
