Hi,
In my case(She's American, I'm French), I sent an email to the consulate closest to her city. They answered within a few days. We weren't eligible for the travel pass but that's probably how you should do it.
If you have the time, you may consider spending two weeks outside the Schengen area to be able to enter the USA, if you have an ESTA(that's what I plan on doing).
Best of luck
