On the topic of government background checks.
Several months ago I applied to the BATF for the privileged of exercising my 2nd amendment right to own a sound suppressor.
They sent my forms back in part because I had failed to certify my US citizenship.
(You'd think that would be part of the "background check")
Any way the form I had to fill out to accomplish this all important task was as follows:
One line with the name of the person being certified as a citizen, which is me.
Another line where I write in the name of the person certifying the person as a citizen. Which after a phone call to the ATF for instructions, turns out to be - ME.
Then my signature at the bottom of the form.
Now in the eyes of the BATF, I'm an official US citizen.
I am not making this up.
