It might only show that they found a bargain flight..
Their problem would be crossing the States. We've always had illegal migrant workers in the Midwest, to pick tomatoes, green beans, etc. The farmers couldn't get along without them, so if Trump bans all of them, the farmers will certainly be hurting and so will the consumers.
Damn that’s a good idea! We don’t need a wall on the southern border. We need a tunnel from the southern border to Canada!
Hell I’d even suggest trains through the tunnel. No 2000 mile hike for anybody! But then the US would need two walls.. ok bad idea. :)
