There are two steps required for NSF checkin-in:
Everyone must stop at the Visitor and Reception Center, on the first floor, to receive a visitor pass. Photo I.D. is required. To access the reception center, cross the sky bridge and walk downstairs to street level or enter from the north entrance on street level.
Bringing a computer? Read the NSF Computer Security Policy and follow the directions. Specifically, if you want to access the NSF network, make sure all virus definitions are up to date and that your computer has been scanned, or NSF IT Help will ask you to complete these activities before proceeding to the workshop. Staff at the reception desk will direct you to the NSF IT Help offices, which open at 7am.
