I am travelling to the US next week and want to check I have it right about how the ESTA system works.
Other answers like this this one, describe what the process is and how to apply, but do not explain how it is actually implemented; what exactly you do at customs or what you need to print or bring.
I have a UK passport. I have registered with ESTA online and submitted the form. My application was approved and when I go on the ESTA website, it says Approved.
So is that it? I just get off the plane and go up the immigration officer with my passport? I don't need any stamp, any e-mail, to quote any number or anything? It's all done electronically?
Believe it or not; I can't find any definitive description of the process online. There are just statements like, "You must get ESTA approval before travelling, etc." - statements that assume you know what that means, exactly. So if anyone has recently travelled to the US using ESTA, I'd be interested to hear if I have it correct.
