To everyone still waiting, hang in there PPR will come one day.
If you haven't already ordered GCMS notes I strongly suggest to do so. You have nothing to lose by ordering them (just $5) - it DOES NOT delay your wait time (unless you request a paper copy....do not do that. Just request the electronic e-mail copy). These notes will let you know what parts of the application have passed and you can see if all info was entered correctly.
To those that did order the GCMS notes, take a look at pages 1-3 and look for the heading "Paper File" and under this heading: "Location". Some members of this form have deciphered that if you see HPT: hold for ppt request, it means your file is sitting in queue to get the PPR email and it should come within 2-3 months. If you see something else it means your file has been sent somewhere else in the office for further review. In most cases further review is for security checks. Many things can determine if the applicant will have additional security checks.
