correctly pointed out IF you're unable to meet the requirements to get the retirement/long stay visa in your country before you come here then apply for a single entry regular tourist visa, come here, get stamped in for 60 days, go thru quarantine, then contact one of the many many MANY agents/agencies that will "push paper" and get you first a 90 day Non-O visa (based on being over 50/retirement) and then a yearly extension of stay for the same reason. Most of those agencies do it without you needing to show any banked money at all of your own.
SO your first steps are going thru the "entry request" process to get permission to enter the country, (100K dollars worth of covid insurance, fit-2-fly cert from a doc, 15 day booked stay in an approved quarantine facility here, repatriation flight, get the tourist visa, etc).
