18 U.S.C. § 1546 When I read that it looks like you're not only allowed to check, you're required to, and you can serve time in federal prison if you get it wrong. Again, I'm not an attorney, so I might be wrong. But it doesn't seem like a loophole despite the many claims I'm seeing. I'd like to look into it. Is the loophole idea coming from an article written by an attorney? Can you link to it if so?
