Nexus versus Global Entry
I live in Buffalo, NY so I cross into Canada a few times per year. I also travel internationally (other than Canada) about four times a year (usually flying into IAD, EWR, or ORD). I was thinking of getting Global Entry, but then saw that Nexus is half the price ($50 versus $100), and as far as I can tell, if I get Nexus I can use it at Global Entry entry points. Is this correct? If so, would there be any reason to get Global Entry instead of Nexus? Any additional advantages of Global Entry? The main reason I want it is for the intercontinental trips, not the Canadian trips. I am a US citizen.
Thanks!
