dont worry.. all of us expecting interview is getting this "not needed at this time" .. but if ur notes says interview then it has to be an interview. good luck!
yes for abu dhabi interviews they usually give a general checklist which requires all the docs again.. including all the forms as well. u can pm me ur num to join interview grp.
You dont need two forms. Only single form where u sign for PA and wife in spouse info. I have did for myself n few friends n it worked fine. So dont confuse urself further. Good luck.
