I'm Brazilian with a flight to London, layover in Amsterdam. I'm going to Ams so I'm gonna do a skiplagging over there but I'm afraid of the immigration complaining about this? how is gonna work, everyone of the flight will follow to the immigration for the Schengen area (then I just leave the airport) and then board again to London and see the imigration again over there for the ETA?
Like my question is, at the immigration in Amsterdam they gonna ask for the ETA? or they don't care where I'm going after. helppppp
