As a related side note, a few years ago we signed up for the MX Viajero Confiable, their version of global entry. Supposed to be way cool, like GE, hit the kiosk and GO. So in the T2 we went around to departures on arrival and appeared for our appointment. They took us to the 'closet' behind the INM office where they had a fancy new machine for taking prints and photos AND a retinal scan!. So apparently they didn't have training. It took like 4 hours to get it done. Just the two of us in the closet with INM. So next trip we check out the fancy kiosk. There is a big orange cone blocking it off. So we went in the Nationals line and said we got VC. They asked for the VC card. I tried to tell them there was no card. I even showed them the approval letter than said there is no card, you just get approved and it is linked to your passport. The INM guy refused to accept there was no card. He passed us through and said go immediately to the INM office in Cancun and get the non-existent card. Of course we didn't. And every trip the nice kiosk was closed. Someone said they didn't have the right paper for it to print a receipt?
So we got our resident cards, so we couldn't use the kiosk, which remained closed every time. Then it was announced that the kiosks would now also be available to people with resident cards, so I thought cool. Since our paid membership was still good, I went in to update the records with our new passport numbers. The website was broken. That page wouldn't load for months. I emailed a couple different help email addresses. Only one answered and told me to email one than never answers. Then after like a year, the website came up and I entered our VC number. Not on file. I tried emailing again with the same result.
In the meantime, brand spanking new terminal 4 opened at Cancun. Guess what? It has a brand new VC kiosk, also a brand new orange cone marking it as closed....
Of course in the US, I forgot to update our GE accounts with our new passports. Both issued at the same time. The missus sailed through. Mine failed. After talking to the Customs guys, he said your mismatch was the problem. (just for me though) and I was the LAST person through the regular people kiosk and was stuck in an optional agricultural inspection when the next to the last person on the plane left the customs hall.....
