There are places in the USA that stock NanoVNAs. Based on reviews on the Ham Radio 2.0 YouTube channel, here’s where I bought my NanoVNA. I got it in less than a week.

I’m a Volunteer Examiner for my local ham radio club. We’re part of the Laurel VE organization.
We (three VEs grade each test) do in person testing and then our VEC (Volunteer Examiner Coordinator) submits the scores electronically using an online portal set up for that. Usually a person has access to their license file within 24 hours.
I have a friend in Seattle who is also a VE. His group does virtual examinations. Except for using video conferencing software to watch the person taking the test, it’s the same process. Three VEs watch each person and grade their test and then their VEC submits electronically.
I didn’t even know that the test results could still be done snail mail.
It’s funny what you said about biometrics. When I was working, my boss (who was a very nice lady much younger than me) thought it would be “really cool” if we had fingerprint scanners to enter our secure facility and suggested that I look into it. The group I supervised managed the access control system. A cybersecurity auditor explained to me that they prefer not to see biometric forms of ID verification adopted because once someone has the ability to spoof your biometrics, your biometrics are worthless as an ID. You cannot easily change your fingerprints, facial structure, retinal pattern, etc, like you can a password, pass phrases, PIN, RFID chip based token, etc. So, we avoided biometrics. Do you use them for identification somewhere? If not, the data captured from a Zoom call probably isn’t a threat. Hopefully your license will appear in ULS at any moment.
