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!
For the USA, leave late and follow these instructions on return:
Delays beyond the traveler's control, such as cancelled or delayed flights, medical emergencies requiring a doctor's care, etc. are not considered unauthorized overstays, however, you will need to bring proof of the cause of your overstay next time you travel to the U.S. in order for it to be forgiven. For airline delays, ask the airline for a letter affirming the delay or a copy of your cancelled boarding pass.
