I am so happy to receive PR today
Could not believe it as I was expecting it in December. Thank you to HO for processing it so quickly and to this forum for all the invaluable information.
I have sent an EEA4 application in June, so the whole process took around 5 months. Just a bit of advice - always better send more documents rather than less. Initially I sent my application in April, however it was returned to me month later as I only enclosed the documents proving that my wife exercised treaty rights in the UK, however proof of residence of non-EU applicant needs to be enclosed as well.
Good luck to all of you who are still waiting for the PR!
