Good info. My pals has been doing 2 * 3 months here for a few years on Visa Exempt etc. Last entry from Vietnam he was told to get a visa. He has applied for 90 Day "O" in the UK and had to show 20k GBP in personal account (He showed over 1 million in Investment but would not accept lol). I just told him maybe a METV would be better - maybe not lol (PS: He will not put 800k THB in a Thai bank account even though he owns a 7 million THB condo, a decent car and 2 expensive bikes)
Nobody has reported any issues. The clampdown is for people holding Visa Exempt now for multiple entries and extensions. This is not about visa holders
