You can also book your appointment somewhere in the US, and later visit a Canadian site on a walk-in basis to add the iris scan.

I've read the wiki and only a small number of posts. We'll be moving to Vermont and would be interested in enrolling at the Derby Line center. Do I understand that the wait for enrollment would be more in getting preliminary approval from the central governments than from getting an appointment where I hope the wait wouldn't be so long in a sparsely populated area?

If that would be our enrollment place for Global Entry as well, is there a downside to getting NEXUS for half the price, rather than GE?

If we might as well start the process, hoping not to wait too long after our arrival in April, can we give our future address in the application, or would we be advised to give our current address because they'd be checking it against government databases?

Downsides to NEXUS vs GE is the limitations of interview stations; you need to do the interview along the US/Canada border, and on the Canadian side if you want the iris scan that allows you to use NEXUS for air travel into Canada. Also both governments must agree that you're a trusted traveller, but I don't know that that would be a huge concern.

Derby Line can't do the iris scan, and they're only open on Tuesdays and Thursdays for interviews for 6 hours a day. Although you can do the interview there and get a scan later when near a Canadian station without an appointment I believe.

I'd think you'd want to give your current address when applying. The CBP advises for GE to wait and tell the interviewers if anything has changed after you apply and I assume the same would be true of NEXUS. Personally I'd wait until you were in VT to apply, and get a VT Enhanced Drivers License to tide you over while waiting for the NEXUS interview.

It makes perfect sense to start a Nexus application now, and then schedule your interview for a convenient location once you've moved in April. Your impression is correct - the long pole in the process is the period of time from application to preliminary approval. Even busy Nexus interview stations can offer interview timeslots relatively quickly if one is persistent working the interview scheduling app.

The only requirement after preliminary approval is to pick ANY interview timeslot - even months from now - within 30 days from the date of preliminary approval. Once an interview time is picked, it can be changed anytime to a new date and/or a new location.

Nexus includes Global Entry. There is no downside for Nexus other than it takes longer to get because two governments are involved, and because there are fewer interview locations.

As silly as it seems, it's a very reasonable question to ask. The agent wants to confirm that the applicant understands what it is they are getting by being approved for NEXUS or Global Entry. I guarantee there are people who would ignorantly answer the question "so I don't have to go through customs".

So it's just a safety question so the agent can explain to the applicant what they are applying for if they answer the question in the wrong way.

I am a Canadian citizen with Canadian passport and a NEXUS. I flew to LGA and returned to YYZ last night. I didn't use my NEXUS to get into the U.S. as was with a companion that doesn't have one. I didn't provide my NEXUS info when I checked in at LGA to return to YYZ.

When I tried using the NEXUS kiosk in YYZ to clear immigration, it said something along the lines of "invalid membership" (I don't remember exactly). This happened after you look into the mirror. I thought my NEXUS may have been revoked but when I checked online I didn't have a message or anything.

Any idea on why this was? Does NEXUS inform you online if you've been revoked or how do they inform you?

So, did you end up entering Canada using Nexus after all? I am sure you would end up in secondary if your membership was invalid.

I read JetLife's post to mean he went thru regular processing and not NEXUS.

Most likely a problem with the machine or system. I had that same error about 2 years ago, right when they changed the kiosks.

+1 on this. If it misreads your iris, it will throw out the same error. Got that same error in YYZ a week ago. Changed kiosk and it worked.

Card arrived yesterday. Total time to renew = 2 months + 3 days.

On a recent flight to the US from Canada, and on the return flight, we were warned that airlines are rapidly dropping Nexus as a means of identification.

Nexus is to be used for customs and security purposes only, we were told. Only passports will be acceptable at check-in and at boarding.

Just a heads-up that this is starting to happen [B]now[B].

Which airline were you flying on, and was it that airline's staff or CBP/CBSA officers telling you this? Air Canada's website for example says that a NEXUS card is enough, while Air Transat's says passport is required, and WestJet's is not entirely clear about it.

It was Air Canada. Staff at both ends (YYZ and LAX) told me the same story.

Are we talking about international or domestic travel? If the context is for international or transborder (i.e. US/Canada) travel, that would be a shame, considering Nexus is acceptable under the Western Hemisphere Travel Initiative. By the same token, I guess I shouldn't be surprised that an airline is unwilling to accept a document which is sufficient for crossing a border.

If, on the other hand, we're talking about domestic travel, then surely passports will not be the only travel document accepted at check-in and boarding.
