"I am 50 should, I make Class 3 contributions to UK pension?"

How long are they taking in responding to the CF83? Is there a number you can call to follow up?
 
Fast enough reply time with online application. In my case just over 4 weeks between application and letter confirming class 2. Postal applications seem to take much longer, possibly several months. The important thing now is to get the application in, or to register with a call back from future pensions. Once you do this before April 5th they will honour your application.
 
Thanks, did mine online about 2 weeks ago. Did you get moved from class 3 to 2?
No I was assessed as class 2 from my first application. Miraculously I fulfilled all the criteria having worked in the UK for just over 2 years in the early 1990s.
