Not a Thai visa question, but definitely everything else :)
I'm looking at longer term visas in the region as a fall back for worst case scenario regarding tax liability in Thailand.
The Philippines looks to be the best option for long stay, no tax unless earning in country plus increases to UK state pension whilst in country.
Cambodia offers retirement long stay, no UK pension increases, not sure on tax yet, not resident under 180 days.
Vietnam only up to 90 days, no pension increase. Hope they extend visas going forward one day. Malaysia similar on 90 days.
Any other options I've missed? Thanks.
