The CFI is not medically qualified to comment on your case - Its just a matter
of going to see a CAA doctor who will
take note of the fact that you are a pilot
with solo experience and act accordingly
so should be no problems
It is a great pity you didnt get the licence
issued in SA as an ICAO licence conversion
is quick and easy compared to a student
cross over
Sad to say but you probably will have to do some flying and all exams if you cant return to SA to complete ?
I had the same situation many years ago on return from the USA and the CAA said - it will be cheaper for you to return to the US to complete than carry on in the UK !!
I took option B and payed a high price..
