Well, you don't recall correctly. Entering the United States without permission and or outside a federally approved location is against federal statute. The first offense is punishable by up to 6 months imprisonment. Subsequent convictions are punishable by up to two years imprisonment.
The commission of any offense that is punishable by confinement is a crime. Speeding is usually not punishable by confinement and is therefore not a crime. Entering the United States without permission is a crime and anyone who does it is, by definition, a criminal.
That’s nice to know. Thank you!
