I've actually considered setting up a Mexican corporation to run C2C contracts through for those who want LATAM hires, but the logistics seemed pretty onerous, especially since I don't live near the border. I'd be willing to do a single trip there to finalize everything, but it seems like as a US resident/citizen you'd need to basically stay there for weeks/months while everything is set up, or make multiple trips for each step of the process.

It's hard not to get angry at the company when you see them hiring at median US wages ($100-120k US equivalent) but specifically refusing to hiring folks in the US, when the company is US-based.
