I'm in New Zealand for a short visit but normally live on board a yacht currently in Greece. My Turkish wife has been given 2 schengen visas so far by the Greek embasy in Izmir. The 2nd of these has only 12 days left before it expires. On the way back to NZ we visited the Greek embassy in Izmir so as to organise a new visa. We were informed that this was not possible until the days left on the previous visa were used, and at this time she would need to return to Izmir for the new visa. Our plan after flying back from NZ to Greece was to sail to Italy. Returning to Izmir will be possible but awkward and expensive because she will have to fly.
