> That's easily available for remote people.

Not easily at all, clients usually avoid working with offshore freelancers directly, and established freelance platforms tend to cap the overseas rates (because they want their cut and also clients expect offshore devs to cost much less)

Or am I totally wrong here?

My experience is, as I read the job ads, they want US based remoters for the easy accounting. So at the minimum, one would have to set up a US company. At the "easiest for the employer", one would have to bill/apply and work through a US resident.

If someone has other solutions for out-of-the-US, non-US-tax-reporters to applying to US remote jobs that list "US based" as a requirement I would love to hear about it.

You don’t present as a freelancer, but as a remote employee to get access to these sorts of things, for the exact reasons you correctly stated
