We must all bow to your expertise, escondida.
Clearly you completely understand the situation and have spent many years living in the US, particularly Texas, and understand its culture, laws, rules, pros and cons, etc.
LOL at parents like mine, Mexican American, 'working with me' if I went behind their backs to do something potentially life-threatening.
I thank them very much for setting firm boundaries for me as a teen and being parents, not friends, always looking out for my best interests and doing their best to protect me to that end.
I have and have always had the utmost respect for them for that. It made me a quite sensible person early on.
My niece is also Mexican-American. Age 18. In Texas. I'm just now telling my sister, her mother about this. Her first reaction is that it is dodgy as hell with big potential for serious repercussions.
It speaks volumes that this girl's parents have made no move to ever meet this bloke, even online, and she has been talking to him for two years and living with and near them.
