Another HUGE disadvantage is the time it takes to be conditionally approved. Global Entry usually takes less than a week. We have reports of NEXUS taking anywhere from 3 to 12 weeks. The approval time varies quite a bit. And we can safely assume that Canada is holding everything up because the requirements, in the eyes of CBP, for NEXUS and Global Entry are identical.
