Transiting Through an EU Airport Without a Schengen Visa: My Experience in Lisbon

#JennAcrossWestAfrica #30to30 #ECOWAS

What I learned the hard way, and how to avoid the same confusion.

I recently transited through Lisbon on my way to Praia, Cape Verde. I’m a Nigerian national, I don’t hold a Schengen visa, but I do hold a residence permit from an EU country (that’s not part of Schengen). I expected the transit to be simple. It wasn’t, so here’s what happened and what I’d tell anyone in the same position.

1. Check your transit requirements before you book

Nigerian nationals generally need an airport transit visa to pass through Schengen airports, unless an exemption applies. Some residence permits can exempt holders, but this depends on which country issued the permit, so don’t assume. Check the official EU or the specific country’s travel information site (for my case Portugal – Transit Visa Requirements and Exemption) and the airline’s requirements, and confirm with the airline before you fly.

For my case, although I require visa as a Nigerian passport holder, however, because I was a resident of EU (non-Schengen), I could transit the airport, but remaining at the international transit station, and connecting my flights without passing the border control.

2. Know what “transit” means at the airport

At Lisbon, I came out of the arrivals area and tried a physical check-in desk (just before immigration/border control) and the system told me I had to pass through border control. That was the first moment I realised my situation might not fit a simple connection. If your connection requires passing through Schengen border control, don’t assume you can check in at the checkin stands and continue. Stop and ask.

3. Don’t rely on one person’s answer

Staff at the airport gave me different answers. Some didn’t speak much English, and I was passed between several people. I was told I needed to go out through the border to check in at 4AM. Eventually I was asked to go to the border control and speak with them. One officer let me through the border.

“This was after I had mentioned that I was not sure if I had the right documents to pass the border and I was only looking for way to check in and connect my next flight from Zone N as the board was directing. Not sure if it was the language barrier that complicated things or if I’m actually permitted to pass the border, but I was let through with my EU residency. I was confused and unsure about the officer’s decision. Also, with immigration, I was concerned that if things escalated or I was stopped while trying to check in or pass immigration back into departure gates, I was likely to be in potential trouble even when it is not my fault.”

However, from my understanding, I’m not supposed to pass the border, so I approached another officer as I walked past the border control. He also initially thought I was fine to go but when I pointed out again that I did not have a Schengen visa, I could see his eyes light up and he realised I wasn’t meant to pass border control. He was gracious and took me back though the border control and back towards Zone N, and one of the security support advice him to ask me to try online check in, which skipped my mind. Once I completed the online check-in, the officer took me to Zone N and I was cleared by the Zone N security and went my way to the waiting area.

Get clear answers in writing if you can, and keep your documents and booking confirmations ready. Ask the airline’s staff as well as airport officials.

Try online check in, so that all you need to do is check in online and move straight to the departure zone listed on boards for your flight.

4. Be patient and polite

Everyone I dealt with was trying to help, even though the process was confusing. Staying calm and cooperative made the difference.

5. My takeaway

Verify your visa and transit requirements with official sources before you travel. Don’t count on being waved through. And if the process isn’t clear, ask until you get a clear answer. What felt like a stressful detour ended well, but I don’t want anyone else to rely on luck.
