. Sorry guys my bad. I read it wrongly..Although other than having no seven day grace period, my answer is basically the same. There's no set pattern and it seems to be a discretionary action by the immigration officer. I do know one guy who lived in the same condo building as me who was denied entry and returned to Phnom Penh, but he'd been here on the amnesty well over a year ago, and then successive covid extensions. Altogether he'd been in the country since covid started, so his time is done. He was told to get a proper visa or try again in six months
