Not that it affects me (luckily!), but I was wondering what happens with countries such as the US, which require a visa to enter.
If you were coming up to the end of the stay, and due to the closure of Northern Europe airspace, had to stay on, would there be problems when then leaving the country?
I've had a search around, but can't seem to find any information on it, and am curious.
Any pointers/information from people would be welcomed!
