Let's split some hairs...

Here's how it works on Sabine. Launch out of Texas - fish by Texas rules. Launch out of LA, fish by LA rules. Obviously you have to have valid licenses, but that's the way it works. I have confirmed this with wardens on both sides of the border and received the same answer.

If you're really that concerned pick up the phone and call a game warden - they're more than happy to help.
