Yeah, it's not much of a consolation, is it?Always wanted to start accumulating stamps in my passport. But not like this
Well, you're only going to get a stamp at the first Schengen arrival point - so usually Lille/Paris/Brussels/Amsterdam for Eurostar.
Yes, the immigration controls will be performed at the same places they already are, so for Eurostar journeys to the continent you'll receive a French entry stamp stating "LFT LONDRES" (Liaison fixe transmanche London). On the return trip it will be a departure stamp from France ("LFT PARIS NORD" or "LFT LILLE EUROP" as appropriate) or Belgium ("BRU - ZUID/MIDI"), etc etc.I presume the stamping (if it will happen) will be done at departure in London, as that is where border checks are and will be done.
Once the new Euro-ESTA thing comes into play, will they bother stamping or will they just use the electronic record from that?
They most certainly should be stamping UK passports come 01/01/2021 as you'll all be in the "Other Passports" lines with the rest of us unwashed masses being treated the same way! However yes the introduction of ETIAS, which is currently expected "by 2022", will end the routine issuance of Schengen entry and departure stamps for most people.I doubt they will stamp UK passports.
