It depends. If you hold only one passport, then the card will show that passport and it should be fine. If you are a dual citizen, the card will show the passport of one country and not the other in a regular lane. So if you are dual US/Canada and you applied through the US side, your Canadian passport does not appear when entering Canada and Nexus will not be enough if you state you are a resident of Canada. And vice versa.

GE with kids
 

I thought if you have Nexus you automatically had GE? Transiting in the US from CUN last week, my 16 yr old, my wife and myself could use the GE machines but my younger two kids had the message that they were not enrolled in GE and we had to stand in the 45 min line. Am I missing something/steps? Or is there a age restriction for GE?

They just need to have had their fingerprints taken. If they were under 14 when enrolling NEXUS, their fingerprints may not have been taken. You should be able to visit a US enrollment center to have them fingerprinted.

Thank you, you are correct. I called and they said my 4 yr old cannot have fingerprints taken and we should use the crew line.
For my older kid, I have to go in to have fingerprints added as she was too young when she got her Nexus/GE.

Report:

Arrived 45 minutes early for appointment at Sweetgrass. Two applicants before me didn't show. After my documents (CDN passport, US GC, WA State DL), were "verified" I was brought in immediately.

Questions by US CBP Agent were: confirm your name, DOB, address (permanent and mailing). Was asked several questions about why I wanted it (my parents live in Victoria, as well as for preTSA), but also why my wife and four daughters did not have it (wife just gave birth, didn't want to make the trip). Asked about my place of employment, my travel history, what I did when overseas (Peru, MX, UK, IRE), etc. Asked about narcotics use (none, that was easy as a teetotaler).

CDN Border guy ran through the "responsibilities" of the program and how one small mistake can result in revocation.

30 minutes all in.

Absolutely right. In my head I was thinking of UA (etc.) flights being credited to Aeroplan or bought on a multi-city via AC reservations, but didn't think through obviously you wouldn't be OLCI with AC for that. Carry on!

I just got approved for my replacement card (stolen wallet). Applied July 21, 2013 and received approval on Aug 27, 2013 - not bad - less than 6 weeks.

I already have an interview scheduled (just called the enrollment center and they manually slotted me in for a interview date). Can I use the GE machines without he actual physical card. I know I can, but is it allowed? I know the conditional approval clearly states that you cannot use the nexus machines.

I'm not sure why this is an issue. It would be no different than visiting the US with just your Canadian or US passport. If the US only sees your American passport details, and the Canadian side only sees your Canadian passport details, this shouldn't be an issue.

FWIW, I have crossed several times in the non-NEXUS lane and I didn't have a single passport on file and it never caused an issue.

I do this almost weekly. Arriving @ YVR from a domestic flight, I walk out of the secure area, via the international terminal to the US check-in area. Enter the security checkpoint as if I was a YVR originating passenger. A YVR agent will scan your boarding pass and confirm your checked bags. Proceed through security. Nexus line may or may not be open at this checkpoint. Then use the Nexus/GE machines in the Pre-Clearance area, talk to the CBP officer and then you're in the secure US Pre-Clearance zone.

You just add your trusted traveller number (the PASS ID on the back of your Nexus card) to your FF profile or into each reservation on participating carriers. Participating carriers are basically the major US carriers (think its AA, UA, US, DL, Alaska).

Precheck has been available on international itineraries on participating carriers for quite a while now, IIRC since May. I've definitely gotten it on all of my YYZ itin's on UA since then.

I too have done this on several occassions. No problem whatsoever.

I'm a little confused here. Conditional approval is different than approval. You also have to do an interview to replace a lost card? That seems super strange. If you're not approved, then I doubt you can use any machines.

If you're actually approved, you can use GE machines without the card.

Sorry,
So basically I had a Nexus card, however, lost it. Applied for Replacement on the GOES website on July 21, and got conditionally approved on Aug 26. They'd like me to come for an interview, however, the enrollment center manually slotted me for an earlier date cuz they knew mine was a replacement - I had to call and explain my situation.

But good to know that I could use GE without the card.

As has been said upthread (what, you didn't read the 7000 posts? :D) some ports of entry do require the card.

Your post/profile doesn't say where you live, but for example, at YVR, the CBP officers require Canadians using GE to present their cards to the officer.

Does anyone have any recent experience with this scenario?? My current passport expires November 13, 2013 but my interview isn't scheduled until December 9, 2013.

I was going to go to the interview with my expired passport, as this is the information that I gave on my application, then apply for a new passport immediately after the interview (pay to expedite), and then update the information in GEOS.

But I'm travelling on December 24, so it would be great if I could have my new passport before my interview!

Thanks.
