In Atlanta it is a big hall for the Passport checks (not customs, that comes later after you collect your bags).
For first timers, they will take your fingerprints and photo at the booth where the officer checks the passport.
It is very swift and easy. I don't remember exactly if there were restrictions about who may use the line, but I don't think so.

You can both go to the same passport check booth, but if you are asked to go to additional screening, whomever is with you will likely not be allowed to accompany you, even if it is your spouse. That person will then have to wait for you outside the immigration area.
