Does My Non-O Visa Transition to Amnesty Automatically After 90 Days?

First of all, I apologise for asking the question as I'm sure it's been asked many times. I'm new to the group however. I have a multiple entry non O. My first 90 day entry on the visa expires on the 27th of May. Does that mean it goes over into the "amnesty zone" without having to do a nightmare trip to immigration or I do have to go and get something done until the borders open?

Thanks once again and apologies for a surely repeated question.
