Hi Ellie to emphasise your comment...
"Check the latest requirements for an extension based on retirement at the local immigration office 3-4 months in advance"
This point may also help Kerry (above)
Thanks for your guidance in the past. As you know we came from UK on OA, did the bounce to Vietnam and back at end of first year and now plan to extend at end of second year at Immigration in September. We hold +800K in Thai bank have required insurance cover and have necessary TM30 and TM47s so...
Why check requirement only 3-4 months in advance, Immigration's policies can change at any time so I would suggest a bit of over-kill and check every month from 4 months in advance right through till the last month of extension request.
Or am I just paranoid LOL 😜
