I am looking to enroll in Global Entry for the first time and I do not have an interview office near me. I plan to do Enrollment on Arrival on our next international flight. Can anyone update me on hours for Enrollment on Arrival at Atlanta (ATL). Customs & Border Protection site indicates "5:00 a.m. to 7:00 p.m. and until all slots have been filled. (F Concourse)" My flight currently has an arrival time of 6:53 p.m., so I am doubting that I would make it to the line by 7 p.m. accounting for deplaning. Is it based on being in line before 7 or arrival time?
