U have to fill form 80 it is must .
Just write which visa u currently on .why u staying write - for better life and better future. That is the appropriate answer to that Q.
be care some Q are not for 887 applicants.so u might have to jump to different section of Q.
So my advice would be .start from Q -1 AND make sure u only fill what u suppose to answer. And skip to other Q . do not answe anything wrong .it will delay ur file and .make confusion.
