I pretty much agree with what Seja said but I do have have a question with point C .
C) why do you panic if something in your application process is different from other peoples application process? They are recruiting worldwide, thousands of people everyday are screened, so the laws and rules for an application process differ and vary in each country and between recruiters/recruitment agencies!
What about the its different from someone that made it to the F1 in the same day and city as you ?
For example - I have been waiting 3 weeks and heard nothing , but another guy in my groups status changed to AIP and he got the tattoo dec also after a week or so from our FI
Since I have heard nothing and my status is still Under Review , is this for me a bad sign ?....
Good luck to everyone about to go to an OD and congratulations to all who got the GC xx
