Thanks for your input, it's very much appreciated. She would actually not fly into JFK, but Boston, but anyways...

Seems like it would be easier if she'd just fly with someone who speaks English, but it's good to know what to expect just in case she would wanna come on her own, and visit her daughter (not son ).

We are well aware of the ESTA, and how that works. She's been here several times before, but never on her own.

Thank you for your reply, I will copy it and file it with useful info.
