Gov site says this
If you are planning to travel to an EU country (except Ireland), or Switzerland, Norway, Iceland, Liechtenstein, Andorra, Monaco, San Marino or Vatican City, you must meet the Schengen areaa_ rules.
Your passport must meet 2 requirements. It must be:
• less than 10 years old on the day you enter (check the ‘date of issue’)
• valid for at least 3 months after the day you plan to leave (check the ‘expiry date’)
I'm travelling to Spain and returning on July 4th. My passport expires 22 November 2022. Which means it will have four months and two weeks remaining on my return journey.
Would you travel with this or would you renew it?
