Apologies if these points are covered elsewhere and thanks in advance for any useful replies:
1) having returned to chiang mai after months out of the country, on a retirement visa (UK citizen), is it still necessary to update my TM30?
2) do I (also) need to complete a TM8 re entry permit?
3) retirement visa expires in January - when is the earliest I can extend it? How long before I apply do I need to have the 800,000thb sitting in my thai bank account?
