going in a few days to Cali, Q r/t nurys & walkthru

So, I am driving 35 hrs to Cali starting this Sat.! I'm scared to death I won't get my walk thru license!

Ok, so I will have with me:

My completed application
passport photo
and verification of my TN RN license

My question is: TN participates in nursys online...but how do I provide proof when I'm trying to get my temp walk thru license? Can I print off a receipt from the nursys website? I never received anything when I did it online, so this is my only proof. Or will they at the board actually look online for me?

And then, do my fingerprints & that is it right??

I'm clearly scared here. I just want to make sure I bring everything I need!
