We have not heard of any word about the extension deadline being extended another round.
So if your visa expires soon apply ASAP, or prepare for alternative options to prolong your stay.
If you wish to use our services, and your current covid visa extension expires before October 10th we can assist with a 60 day covid extension without losing any days.
Plenty of travelers have reported trouble obtaining a 60 day covid extension directly on top of a visa exempt entry / tourist visa, and are pushed to first apply for a 30 day extension they should be obtaining.
Your experience confirms that it is possible to apply on your own, but the general consensus at the moment is that not currently the norm.
