Hi Craig,
some folks joining us for the 2019 pre-worlds at Stendal were walking through this process and unfortunately, non-EASA licenses are still only validated for a period of 4 consecutive weeks ("holiday licenses").
From this recent experience, I can confirm that the information given on the AOPA website is still valid.
Best regards,
Christoph
PS: would be great to have someone from the US joining for the pre-worlds - there are still slots available (
