Ask HN: Remote/Global Work

I am an exFANG senior sw engineer living out of US due to things out of my control(family, health and finally covid). I got offers with in US but nothing pure Remote or should I say Global. What is the best way to get a Global/Remote job? Do YC startups accept developers out of US? Can having a LLC in US or with in the country you are in helps to find a pure remote/global job? Why a developer can make more than quarter million dollars in US but nothing when out of US with the same skill set and contribution chance?
