My husband recently became a US citizen and just got his US passport yesterday. Does he need to re-apply for Global Entry or can he log on to the GE site to update the passport information? Thanks!

Actually, does he need to make an appointment to go to the center to update his citizenship information and passport? Or can he just show up to the center?

UPDATE: hubby was able to walk in at the center in Long Beach, no appointed needed. Brought his US passport and GE card. Finished updating in less than 10 minutes! Whoohoo!
