We are a family of 3 taking direct train from London St Pancras intl to Amsterdam which has started in April 2018. We have valid Schengen visa already and we hold Indian passports.
However I have a doubt about exit from UK and entry into Schengen. Will our passports be stamped accordingly ?
Later from Amsterdam we are taking train to Paris and than flight to our home country. Will it be a smooth immigration from Paris if our passports are not stamped inward at St Pancras intl ?
If someone who has taken this journey can clear our doubts. Thanks
