Just in case this helps anyone:
My appointment today took 30-35 minutes.
I was asked to read a poster ensuring I have not been in contact with anyone showing symptoms and that I myself did not have symptoms. I think they will turn you away if you say yes. None applied to me, so I replied no.
I was asked to use hand sanitizer several times throughout the process.
Each station where fingerprints and photos are done were sanitized after each client left.
X's were marked on the floor to keep people in line at a distance from one another and seating areas were spread far apart as well.
I am unsure if all US states are taking these measures, but did want to let people know my experience in case it helps someone.
