If I have a piece of advice to give you, it is to be well informed on the compulsory administrative papers before taking your flight (if you take it at the last minute) or a few months before your trip, Especially before the trip do: sort it in your wallet and take only the useful papers. two photocopies of your papers that you take on a trip (if lost this will be very useful): one photocopy that you leave at home and one that you take with you apply for the European CPAM card online (it takes a few weeks to receive it, but in general it is quite fast) check if your identity card or passport does not expire soon, beware the extension of 5 years for the identity card is not taken into account in most countries
