I am in NYC right now and have been since Friday the 9th. I traveled with a friend who booked return tickets, and we were scheduled to leave on the 16th. I have, however, been asked to hang out with a lot of cool people and decided to stay a little longer, so I simply didn't board the plane home with him. I have instead bought a one-way ticket to go back to Denmark on November 9th.
I'm worried, however, that this is in breach of the terms of my ESTA (which is valid for another 14 months), and that it will result in my being banned from reentering the US later on. What should I do? Is there a government agency I can call/email to show proof of my planning to leave the country?
I'm a Danish citizen and resident, and I have no plans to extend my stay further.
