Hi Guerrich,
My understanding is that within these '3 months' the VO should have contacted you (based on all the other PR members previous to 2012). Within these 3 months, they would have assessed your file and asked for additional documents, missing documents, payments, interview etc. Best case scenario, they would have given you PR within these 3 months. However, with Berlin office closing and summer holidays, Monikita has passed her 3 month mark and I'm almost there. No one has contacted either of us for anything. I believe they'll eventually respond saying your file is 'in process'.
The 7 months is the average time it takes for them to process PR applications. I believe that is what they send everyone originally from Berlin Office. I say this because our file is originally from Vienna and it says average processing time is 9 months. Therefore, they are only stating CIC statistics....
Hope this helps
