I've had auditors tell me anywhere from 3-6 months depending on what is being looked at, and on what review schedule your own programs are based on. SQF Food Safety (formerly SQF Level 2) has several annually reviewed programs- Food Defense, Mock Recall, Crisis Management, etc. I would suggest doing a good code read/review to see what the requirements are, and to see changed when the code updated to Version 9.
If you feel you have all the relevant, annual reviewed materials completed in 3months of implementation, then I would get in contact with a CB. Regardless your first step will be a desk/paperwork review, and they'll let you know what is lacking.
If not, I'd spend some more time reviewing and insuring you have met all necessary criteria. There is no sense in spending the month to find out you're missing half of your necessary challenges/programs.
