Dave you are confusing 2 different extensions.....1. Marriage extension...400k for 2 months before...and usually keep it for a month after to be safe (it has never been 3 months before and 2 after)
2. Retirement extension...800k 3 months before application and 2 months after, mandatory for every renewal. (also min 400k for the other 7 months of the year)
You may be told to leave at the end of the amnesty regardless of where you are a resident. :( They would expect you to return to where you are a citizen :(
This is why I have continued with normal extensions, even though I could have been covered under Amnesty. Don't want to be told to leave the country, if that happens. Have been, and will be, continuing my extensions. What if they need a huge insurance package, or 14 days paid state quarantine, limit who can return to Thailand by nationality, have to cross a border and then have no flights to anywhere, be stranded in that country......so many scenarios that could happen....I will be staying the course thankyou very much ;)
