I have a really tight connection in DFW next month: how long does it take to get approved for the NEXUS card? When you apply online, how do you provide the documentation--do you scan it in or just show it at the interview? Does the interview have to be scheduled between the hours of 9 and 5, or are they more flexible? I live nowhere near an international airport, and my flight departs at o'dark thirty in the morning...not sure it's something we could do before departure.
