aor IS MARCH 2017 ? This is very long waiting. My AOr was 22 march 2018 and I have got PPR on 14th August 2018. London Visa office . PNP paper based applicant.
If your IELTS score is valid till December 2018 then why are you being asked again ? I am aware that IELTS is required for business applicants also but the minimum requirement is lower. What was your overall score ? (If you don't mind sharing)
This is positive news. I am connected to paper application Wotsapp group and there are a few applicants with Feb AoR who are still waiting MR but their BG check has started and they have received pre arrival letter.
So, congratulations!
