I've always had to talk to Canada first, then US (at YYZ). I was a Canadian resident when I first applied, and US resident for my renewal interview, so don't believe that makes a difference. I believe that's how the setup always is/was (at least at YYZ).

Wonder if its possible that if the Canadians are busy but US are not, they might swap the order.

AFAIK, even if you have both documents set up in GOES, there is only one that can be set up for you to use in a GE machine - for one with a US passport, it has to be that. I'm guessing (but its just a guess) that they set you up to use your Mexican credentials.

I would try first to call a GE office (since it seems to concern GE, and you will be able to speak to an US officer there), and they should be able to look you up and see how you are set up. Perhaps they'll be able to sort it out on the phone, or perhaps you'll need to go into an office to have the system updated with your Canadian passport.

Crossing the border by bus is perhaps the least pleasant way to travel. There will be no special GE or Nexus benefits. In fact, you're going to wait for the slowest person to get through anyway...invariably someone who doesn't speak English and may or may not have the right visa will take 15 minutes.

I always show my Nexus card, but I don't know if it makes much difference. Sometimes it seems like it may have sped it up, although, I also had my worst border crossing experience ever by bus. Even had to ask for a supervisor once the agent veered into inappropriate territory. Although that was Detroit and not Buffalo.

No surprises there...
I have just tried to contact the YVR office to ask specifically whether I needed to come in and if so needed an appointment, and was told I might get a callback in a week or so.

I contacted the Peace Arch office who said that the NEXUS defaults to US passport, so not to worry about it...

Obviously nothing and no one can be believed or counted on to answer, let alone do so correctly.

I am going through the Peace Arch shortly and will report back on what happens. My GOES file clearly states Expired Document, but it is a document (PR card) that I will never renew.

It would be $19, not $6 :P

haha yeah its going to cost you at least $5 before you even go anywhere.

To compound to the confusion, I'll share my interview experience in Detroit. I attended the interview and my DL had expired since I applied. I brought the new DL and my current passport with me, as required. There were 4 CPB officers and 1 CBSA officer. Each CBP officer had his/her own computer but the CBSA officer did not. One of the CBP officers updated it in the computer but the CBSA officer did not even look at either document. After the interview, the CBSA wrote some info on a form, checked the "Approve" box, and handed it to another CBP officer who entered something into the computer.

Also, there was no Canadian and American "desk". It was one long counter with the CBP officers and CBSA officer sitting next to each other.

I posted it above. Here's the link again: http://www.cbp.gov/travel/trusted-tr...nexus-overview

I have my interview to renew my NEXUS card scheduled in a few days. Since I cannot find a good answer to this question, I plan on using the regular customs lanes into Canada and I will ask at the Enrollment Center what I should do on the way back into the US a couple days later.

It is like you give up your NEXUS card the instant you apply for the renewal. That does not seem logical but I will follow the letter exactly.

I used my existing NEXUS card several times while I had an interview scheduled for my renewal. I had no issues at all. When I went for my interview, they did tell me that I cannot use the NEXUS machines until I receive my new card. I asked if this also meant my existing card because I was going back to the US, and they said it was no problem using my current card as it is still valid until I receive my new card. I suspect that verbiage applies more to people applying for NEXUS for the first time, not for those of us applying for a renewal and in possession of an existing valid card.

I went to the Bills game this weekend by charter bus (all going to the game). There was a special lane for buses going to the game at Ft Erie crossing. US CBP officer came on the bus, checked photos against the holders, took all passports and Nexus cards (several of us used Nexus), scanned them and brought them back. 10 mins total.

That's awesome, but I can assure you that it is not SOP. Normally all travelers exit the bus with luggage and are processed one by one. The luggage is put through an X-ray machine. Everyone then reboards the bus. Never has it been as fast as 10 minutes.

We've had Nexus for a year or so, and used it several times crossing by land, but never by air. We usually drive to BUF and fly out of the US, but this time we are flying to FL out of YYZ on WestJet. The WestJet site asks for citizenship and passport information in order to speed up the check in process.

My question is: If I fill in the passport information, are we obligated to use our passports when going through US customs/immigration at YYZ? Or, can we still use the Nexus card for that? I don't mind carrying both documents if that is what is going to make the flying out of YYZ experience easiest for us.

You can use NEXUS at YYZ (in lieu of passport)

but you should carry your passport, just in case (also as NEXUS requirement)

Firstly - ALWAYS carry your passport with your NEXUS when flying. You are required to produce your passport on demand, and I can tell you from personal experience that you will be refused entry to the US if you try to just travel on a NEXUS card. Had to fly back to Ottawa, find my lost passport, and then return - hard justifying those additional flights to my employer.

Even on AC, which has a field on the Advanced Passenger Information System for your NEXUS PassID number, always requires me to provide my passport at the check-in counter. They don't seem to accept it as complete ID at the counter.

Once I've done that, I simply show my NEXUS card at Canadian security (YOW) and not my passport. At US pre-clearance (YYZ), the new GE machines require you to scan your passport (or you can place your NEXUS card in), but agents always ask for my passport afterwards. And strangely, even stamped it last time, for the first time in years.
