If you have entered by plane you shouldn’t have an issue. If your crossings were by land already, fly out and fly back in. You may have reached the 12 month period for entering by land - but I am not sure how they track that.
Thanks as always Tod! I will try to get a tourist visa from Phnom Penh in may so I will update you how it goes when I do! Hopefully restrictions will get more relaxed by then - but maybe I’ll just fly into Phuket if I don’t get a visa approved!
