I think you can just show up.
This depends on the border crossing and facilities. When I had my interview at Champlain, NY, once I was done, to get my iris scans I didn't have to go to an airport, all I had to do was cross over to St. Bernard de Lacolle, walk into the service building there, and get my scans.
And spend 20 minutes waiting in line to cross back into the US, since I didn't yet have my Nexus card... (shortest visit ever to CA....)
