ESTA question

[magpies]

We are going to the States in a couple of months and now have an approved group application (expires in 2025)

However we are not all going on the same date. My wife is coming over a week after me and I'm the group initiator/contact.

I have forwarded her the US Customs email with the receipt and approved application details. She will have a printed copy, does she just show that along with her passport?

Its all linked to the passport. Its worth taking a copy of it but I have never been asked for it.

Cheers - thank you

You don't need to show it (unless the system is down, which is rare, but does happen).
It is all linked to the passport number, both for APIS, and at your US POE.
