My wife is Thai and I am British.
We got her a visa for the UK - C.Visit, Multi entry, 180 day duration, Valid 6 months.
Also we got her a ETATS Schenngen C, Multi entry, 90 day duration, Valid 6 months.
Now the question!
Arrived in UK 20/10 Entry stamp in passport.
Left UK 23/10 no exit stamp.
Arrived Spain 23/10 Entry stamp.
Drove to Uk via France Entry stamp 16/12 UK at Calais
Left UK 6/1 via Ferry no stamp at port.
Arrived France and drove to spain no stamp.
Arrived back UK 23/2 stamp at airport.
How? can they know how long was spent in europe from the entry into the uk, stamp 16/12 until the next entry stamp 23/2
Is it not possible to gain an extra 56 or so days on your Schengen by saying we were in the UK up until the 10/2 as they dont stamp out they have no way of knowing from your passport how long or when you actually left the UK.
It seems quite complicated but i am sure you can actualy get 180 days out of your Schengen when they only alow 90 days.

Can anyone confirm or deny?
