Nationality: Non EU
Hi, I have a temporary residence permit from Portugal which has expired, I am awaiting the Blue Card, meanwhile, I have to travel to Poland from Portugal. I was checking a flight from Lisbon to Krakow, which has a layover at Eindhoven airport, Netherlands. I wanted to know if I will pass through immigration at Eindhoven airport when landing from Lisbon, because passing through immigration will be a problem. Where can I confirm if I will have to go through immigration or not? Since both Portugal and Netherlands are in the Schengen Border Free zone, I am of the assumption that I will not pass through immigration, but the website where I'm booking the flight shows the warning in the screenshot.
As a side note, I have the receipt of paying for the blue card. Will that be accepted for traveling?
