I am traveling to the UK for a conference. I am flying from Italy on May 19th and flying back to Italy on May 24th. My permit is valid UNTIL May 24th. Therefore, my permit is still valid on the 24th and this may not even be an issue.
I know I am allowed to enter and leave Italy while my permit is being renewed. I show my expiring/expired permit as well as the postal receipt showing that the renewal is underway and the Italians stamp my receipt..this allows me to enter and leave the country.
However, will I have problems leaving the UK on the 24th? It's still valid, but in case they ask will showing my renewal papers along with the original permit work with the UK as well? (I am an American citizen btw). Thanks!
