Thanks, CayeMarie. Now I have looked at the US Immigration site, and am hoping you can give me some directions as to where I would find this information. I will go back and start weeding through it, but maybe you can shorten my search.
I have looked into sending them through Cancun, and we still might go that way, but it sure would be nice to do it be able to do it through the states, so much easier from here. Comox-Calgary-Houston-Belize City. It is also getting really complicated trying to work around her holidays, and getting them enough time down there to enjoy San Pedro.
And I would like to take a moment here to say that I have never been treated badly, or even rudely by customs in Houston or anywhere else in the states we have travelled through. I know a good part of this is because my husband is older than I am and we look like prosperous, tired, distracted Canadians when they see us,but they do have a job to do, and I am sure they don't like attitude any more than anyone else.
The rudest customs person I have met lately was entering Belize last year from Chetumal. The guy was a pushy little shit, and it is a good thing my husband is hard of hearing, I acted as if he was making a little joke, but he really was an a**h***.
