Hi rajan, 

i am assuming you are talking about IELTS. First, IELTS is an english proficiency test required for admission and work related applications in english speaking countries. In case you are aiming for admission, your IELTS academic score would be first taken in account by the university and then by the visa centre. Regarding IELTS general, it would be taken into account by the organisation you are aiming for. 6 band should not be a problem. But you should check with the organistion/university.
