It's NOT those that arrived after March 1 that are in real trouble, as they can still apply for the 30-day 'normal' extension with relatively little paperwork.
But it's those that arrived before March 1, and already 'used up' the normal 30-day extension they were provided. The requirements to apply for the 'emergency covid-19' 30-day extension are preposterous and for many even impossible to meet (e.g. the owner of the place where you are staying, has to be with you when applying for that emergency extension).
It would be funny, if the consequences were not so devastating for those confronted with this bureaucratic madness
