Why U.S.? I understand that you don´t want to live in your country, but there are many others countries. Many of them has a much flexible immigration system where you can live legally if you find a job and where there are many jobs opportunities if you know how to code. I mean, instead of working almost illegally for free in the U.S., you can be legally and earning good money in another country. I´m from Uruguay and this will work here (also, you will have health insurance, as it is mandatory in any job of any type. Also, it is common that tech companies hire forgeries that don´t know Spanish, as most people know English, is not a problem). I know that this is also the case in many other countries.
