I am coming up to 90 days in the EU (Italy, Ireland and the UK):
Italy is part of the Schengen zone (there spent 30 days)
Ireland is NOT Schengen (30 days)
UK is also NOT Schengen (30 days)
So my 90 of 180 days in the EU is just about to be up and I do not have a visa (US travelers are not required to have a visa for 90 day stays abroad in EU - only a passport).
I want to go to France next (part of the Schengen zone), would I have still 60 days left to do so, or would my total European stay have eaten up all of my 90 days?
