The Immigration Act 2014 contains, amongst other articles, a description of the requirement for Exit Checks and outlines that the government will require "Carriers" to be responsible for the process of the Exit Check at the point of departure. The Government defines an "exit check" as "a check that satisfies the Government to a reasonable degree that an individual has left the United Kingdom".
In reality, they are asking for a scan of the MRZ on each passport backed up by verification (face to passport photo) of a certain percentage of passengers. Eurotunnel Le Shuttle will launch the process on 04 April 2015 in order to meet the government requirement for the formal commencement of checks from 8th April.
Having passed through the Check-in Plaza at Eurotunnel Le Shuttle's Folkestone Terminal, coaches must proceed to the parking area for high vehicles adjacent to the terminal building. The direct route to shuttles will be closed to coach traffic.
On arrival at the entrance to the high vehicle parking area, coaches will be guided to the entrance to a new passport control area located inside the terminal building.
A Eurotunnel Le Shuttle staff member will ask the coach driver which category of customer is being carried in the vehicle. These categories have been defined by the Home Office and are shown below.
Where an Exit Check is required, customers must disembark the coach and enter the passport check area in the terminal building. NOTE: the coach driver must inform passengers either to return to the coach immediately, or in xx minutes, as required, and should check that all passengers have disembarked from the coach. He/she should assist customers with mobility impairment to leave the coach.
The coach driver should then move the vehicle to the parking area for coaches and then proceed to the passport check area to have his/her own passport scanned.
Coach passengers will return to the coach following the route prepared for them. The coach park layout is being modified to ensure it is safe for customers.
