Indian here with a single-entry Schengen tourist visa. I'm planning to visit Iceland (first port of entry) then Europe with a connecting flight via the UK (non-Schengen). Can I travel between Iceland and Europe with a connecting flight in the UK and still roam around Europe or will I be stamped out and not allowed into Europe?
Do not do this.
If you travel Schengen to Schengen via Non-Schengen what will happen is the following:
- You will get a Schengen exit stamp in Iceland, as you are exiting the Schengen Area.
- You will thus have used up your single entry, and can not reenter.
- As a result, in the UK you will be refused boarding for your next flight, and will be put on the next flight to India.
A few Indian collegues of mine had exactly that happen to them. They were spending two weeks in Sweden on business, and decided they wanted to take advantage of the weekend to see Prague (indeed, why not?). But they booked a flight via Kyiv, as that was cheapest, and ended up back in India earlier than expected...
