Passport Question

Unfortunately, you'll only get stamped upon entering the EU through London and existing out of Munich. Going from country to country within has been seamless for many years now, which means, no stamps :(

You will get it stamped when you arrive in London for the U.K. Then when you go through passport control at St Pancras station before you board the Eurostar, you get a Schengen zone entry stamp. You will get a Schengen exit stamp before boarding the Munich flight back to the US. That's it. You can't get souvenir passport stamps anymore. They are legal entries into your passport. France, Netherlands, and Germany are all in the Schengen Treaty zone, so you get one stamp when you enter and one when you exit. Anything else would be considered a "defacement" of your passport.

So to be clear:
Stamp upon entering London
Stamp upon entering Shengen St. Pancras/Paris Nord
Stamp upon leaving Shengen in MUC

Correct?

No, incorrect. Sam is correct. EU and Schengen zone are two different identities but they overlap somewhat. London is currently a part of the European Union but not part of Schengen zone. You will get an entry and exit stamp for Great Britian. You will get an exit stamp in Munich since you are leaving the Schengen zone and a Schengen entry stamp in London just prior to boarding the Eurostar. No stamps in Paris or Amsterdam. EU is an economic agreement and Schengen is immigration and customs agreement.

PS Passport stamp are not what they used to be. The Schengen entry stamp in London is about the size of a quarter.

Okay, so:

UK Entry stamp at LHR
UK Exit Stamp at St. Pancras
Shengen Entry Stamp at St. Pancras
Shengen Exit Stamp at MUC

Now you have it. Small note, it is Schengen zone

PS One more comment. It is absolutely critical that your entry and exit stamps match up. There is a limit of 90 days out of 180 days that you can be in the Schengen zone. You do not want an open entry stamp with no exit stamp.

Not sure about a UK exit stamp at St Pancras, somebody with first-hand experience can elaborate. I assumed that a Schengen entry stamp at St Pancras would automatically imply a UK exit, but I could be wrong.

I'm happy to be proved wrong but I don't think you get an exit stamp when leaving the UK.

Aaaand I can't spell. :)

Thanks all! Was just curious as to what I would be getting! It's my first time heading out of the country (minus once across the Arizona/Mexico border), so I'm pretty excited! 3 days in London, 4 days in Paris, and 3 days in Amsterdam!

It is a combined stamp. It is in French. Shows the entry arrow in the box, shows a train, and has LFT LONDRES A151 next to the entry box. Assume the A151 refers to St. Pancras but there is no other information as where the stamp was given.

Kevin, The UK does not do exit stamps, only entry. It is the responsibility of the transport company to check your passport and log it in a database, but they don't stamp it.
You first list was correct, you will get three passport stamps (assuming you are not an EU/Schengen citizen, who never have their passports stamped):

• UK entry stamp at the airport.
• UK exit - passport checked by Eurostar staff at St Pancras, but NO stamp.
• Schengen entry - stamp by a French border guard at St Pancras, just walk off the train at Paris.
• Schengen exit - stamp by a German border guard at Munich airport.

Train Paris to Amsterdam, no ID checks at all (France/Belgium and Belgium/Netherlands borders).
Flight Amsterdam to Munich, ID check by the airline, you will need to show your passport, but only as ID.

Great Britain does not give exit stamps. The stamp you get at ST. Pancras is your entrance stamp into Schengen.

I was curious, so I looked at my passport for stamps from a trip a couple of years ago. I have an entry stamp at Heathrow. I then took a train to Scotland, then flew to Barcelona, where I got an entry stamp. Then I took a train to Madrid. I have an exit stamp from Madrid and an entry stamp at Gatwick. I left the next day from Heathrow, but have no further stamps. So:

• entry stamp Heathrow
• entry stamp Barcelona
• exit stamp Madrid
• entry stamp Gatwick

To be clearer, at St. Pancras you interface with French immigration officials, not British ones. When you leave the train, you just walk out the station doors, no passport control, no customs.
