I will be visiting the US for a short period of time in july, I was elegible for the VWP so I applied for ESTA and it has been approved.
What should I bring with me when traveling to the US to demonstrate that I am authorized to enter the US under the VWP?
Is a print of the report from the esta website enough or do I need some more documents?
Note: I will obviously bring with me my passport, driving license and other identification documents.
From the US Customs and Border Protection website:
The United States regulation does NOT require a Visa Waiver Program (VWP) traveler to present a printed copy of the ESTA authorization page in order to travel. However, it is recommended that you print a copy for your records.
I carted around a printed copy for my first few visits to the US but it has never been useful and I have long since stopped.
That page does continue:
Some airlines may ask you to bring a copy, in which case you should print it out.
I think the key word here is ask - I never have been. Worst case, you could retrieve the details from the ESTA website even if you can't remember the application number, assuming you're travelling with a smartphone.
