I'm living in Germany with a blue card. Some days ago I've come to Korea but I forgot to take my blue card. I'm going back to Germany from Incheon airport (Seoul) and will stop over in Heathrow airport (London) and will go back to Tegel airport (Berlin).
How can I go back to Berlin without my blue card? I can ask my wife to bring the card to Tegel airport if it would help, but I'm not sure if I can take the flight at Heathrow airport or even at Incheon airport.
I've asked via another channel and just got an answer saying that he had accidentally put his blue card in the baggage but he was able to enter the country after the security guy checked through the system. That said, more official answer would be welcome.
I've come to Germany without any problem, but it was possible as I had Beiblatt attached to my passport, which has the expiration date of my visa. The staff at the check-in desk has checked the document and the German border guard also has checked it. Nobody asked me for the blue card in my case. So I don't know what would have happened if I had neither.
