My meaning is: she needs to prepare for an interview

EB applicant may be required an interview,if you search with " interview'or "local' on this forum,you may find out a lot of post,many of them base on EB.Usually the interview is different with the interview for citizen spouse,it's simply & easy,but you
can't say that: the applicant probably won't be required an interview since he/she is an applicant base on EB,if the officer think that an interview is
necessary.
