Sammann :; As per past records of ND , Interview letter usually comes from 9th to 11th month from initial Date of Receipt at Sydney. Looks like you have passed that "Lion country" Even if we are 100% Genuine cases interview is really scary but here we are 100s of members to guide you. If you guys are honest nothing to be scared from. If applicant has a long history of travel, that could be a reason of delay as security checks will be done from all those countries. I read a major delay case file held for background checks for many months and this reply they gave to an MP.
