yes you need only to prove the 500k at application and reason for the visa.
Remote worker , programs etc.
At this point you only need to prove the funds once, just like a 1YR OA VISA, multientry and can be stretched to almost 2 yrs with bounces.
But if you extend in country you need to meet the criteria again.
It is a bit of a too good to be true scenario right now.
My opinion is that there will be changes, but for those that get one now it's golden.
**THERE are varying reports from different embassies on how to prove the funds and requirements, this embassy specific.
Embassies and immigration are 2 separate things.
The embassy grants the visa.
The rules for the visa
entry are under immigration.
So each embassy will decide what you need to get it.
