To bring this back to the top.
I have now visited the Orlando FSDO with all my documents. The whole process took 30 minutes and was free. I used the letter provided by the FAA at Oklahoma - they don't care which office it is addressed to, provided you have one. This letter is obtained after paying our money grabbing civil servants £40 !
They were as bemused as me at the need or requirement for this exercise, however they did confirm that all paper licences will need replacing before next year.
The difference in renewal depends whether you have sat US exams, or have obtained a US licence based on your UK licence - a 61.75 licence.
If you have sat exams and have a stand alone licence, you can renew on line, if not, you need to use one of the UK based guys or visit a FSDO in the States. If you are planning a visit, I would choose the latter.............
Either way, if you have a paper licence - get it sorted now as it will not be valid after next year whether you speak English or Swahili
