Getting a visa to work in the US is a nightmare so I wouldn't advise you look into that. It's costly for the employer, time consumer for both of you and the odds of getting accepted are small. If you were to find some company willing to spend the time and money to get you there through that process, you would have the job you like already and would just have stumbled upon an insanely great opportunity. It doesn't look like that's the case.

Regarding the fact that all the opportunities you find require experience... Well everybody wants someone experience, it's just must faster to get them to be working and productive. That doesn't mean all companies will find that person. Itcould be because there is more demande than people looking for a new job with that skillset or because they don't want to pay enough. When that happens, they'll have to resort to hiring someone with less experience than they hoped for, and that's where you come in. Show that you're good, have some pet projects to show you know something about the language already, be great during the interview and you could get hired.

Job offers describe the ideal candidate, not the mandatory requirements, even when it says so, companies will do with what they get so apply anyway and see how that goes. I never fully met the requirements for the jobs I applied to when I got hired, and it forced me to level up, learn new things and tackle challenges, so it's not that big of a deal and you still have a shot.
