Visa on arrival in Cambodia.
$2000 deposit for covid19 test and first nights accommodation in nice hotel. If nobody on your flight tests positive $1750+ returned next day. You need correct E tourist visa to extend for six months without leaving. I think insurance cover up to $50,000 also needed.
Life in Kampot...it’s hot, it’s cheap, it’s on a river and the beach at Kep is twenty minutes drive on a scooter. About $200 a month long stay accommodations plus bills. Talk to Sean for enthusiastic reviews.
