Medical & Revalidation
I fell between several stools on this subject.
Having done my 12 hrs + 1hr instruction I took my certificate to my usual CFI get signed but was told it could not be because it was more than three months prior to expiry
My medical then expired and when I re-presented I was told it could not be signed because the medical was not current.
Then another CFI advised that it could be signed at any time duringthe second year after I had completed the requirements.
The last seems the most logical to me.
So on with the FAA licence in the meanwhile, no such hassles
