Ask HN: Tips for getting remote work in the U.S. as a foreigner? (W8 or C2C)

I´ve been looking at LinkedIn, StackOverflow, and some job boards, but remote jobs seem to be for U.S. citizens only, and there are lots of semi-remote jobs but they seem to be tired of remote submissions (they say NO VISA, NO C2C, etc..)

I know there are a few job boards for remote-first jobs but they all seem to be frontend-focused (I guess that´s the easiest to outsource?). I´d also like longer-term engagements.

LinkedIn in particular always asks "Are you legally allowed to work in the U.S." and I truthfully answer "NO" as I don´t have a working visa.

Are there any remote-friendly boards I should be looking for? Twitter or some other social media? Make myself available to recruiters? There´s one ad of a company that says they can place me if I spend 40 hours on tests.

Should I lie and say I´m on the U.S.? Stress that I´m available for onsite interviews? How do I differentiate myself? I believe I have very good english and I´m good at what I do. I don´t want to go the H1B route for family reasons, I am willing to travel frequently and even on my dime.

I´m also willing to go personally to the U.S. to interview but I need to have a plan and goals :)
