Ask HN: Opening an FDIC insured savings account in US as a non-resident?

Seems like companies (or rather neo-banks/Fintechs) like Mercury provide an amazing yield while also being FDIC insured at the same time. This is not generally accessible for people who are residing in 3rd world countries. Is there any alternative banks in the US that natively support non-residents to open an account (remotely or in-person but without a proof of address) and provide FDIC insurance?
