Non-immigrant in Collins aerospace

I had recently been laid off due to budget issues and I got an offer from Collins aerospace as an Embedded SWE. I'm grateful. But the tech they are using at the moment is really outdated. ADA language, I don't know if anyone uses this. I have big aspirations to join FAANG someday. Being a non-immigrant and in the aerospace domain, I don't know very many companies sponsoring VISA. I had great fun developing drivers in my masters, wish I could stay in that domain. How should I go about my future ?
