How can expats in Thailand manage visa extensions and 90-day reporting when facing health issues like dementia?

And to build a solid friendship system rather than filling life in with fakes and flakes from family or friends. It’s most upsetting and gross when you’re dealing with flakes

i’m going to a $800 month bangkok alzheimer’s unit. 8 k in usd. a month.

Agents do 90 day for many friends who cannot or don't want to queue. They also can do extension visa, plus have carehomes, hospital and good neighbours/adopted family

Even more concerns would actually be to get a new passport. If you can’t travel to the embassy and have to appear in person - that’s an issue!

For long-term retirees in Thailand holding visas such as Non-O, O-A or O-X, the system assumes you remain mentally capable and financially self-sufficient, which becomes a serious vulnerability if conditions like dementia set in. In practice, once a retiree can no longer manage 90-day reporting or annual extensions, everything depends on whether a trusted person is already in place—someone with power of attorney who can handle immigration filings, maintain the required bank balance, and communicate with the Thai Immigration Bureau on their behalf; without that, even a well-established retiree can quickly fall into overstay status. Unlike some Western systems, there is no automatic safety net or state intervention for foreigners, so if capacity is lost and no one steps in, hospitals, local authorities, or even embassies may eventually get involved, but usually only reactively and with limited scope—often leading to repatriation if funds or next of kin can be found. The safest approach, therefore, is to plan early while still healthy: formally assign decision-makers, keep finances clearly structured for visa compliance, maintain valid health insurance, and ensure someone can act immediately if cognition declines, because once that tipping point is reached, the system becomes administrative rather than compassionate, and options narrow very quickly.

I feel sure my Wife and her family would look after me if I became iincapacitated

Dealing with Immigration also

90 day can be done on line

Yes, but switching means 800K in a Thai bank which is your guaranteed health Insurance and with no interest. Its alot of money locked up doing nothing!!

might not be popular, but if you can't handle it and don't have a caretaker that can't handle it. You need to go back to your old country because they will take care of you. The Tai government has no obligation to take care of a non-citizen. When I can no longer take care of myself I will not go back to America I will do myself in

Generally they die alone and miserable.

For me, this post highlights the importance of learning thai language and being able to communicate.

My wife and I are actually building an assisted living home for expats. Proper care places should take care of all of this for you. It can get into power of attorney and medical power of attorney, or if the immigration office is lenient sometimes a care person from the facility can handle things. But a lot dont... thats why sometimes you will see someone who is incredibly aged at immigration.

This is one thing that a lot of people do not look into when looking at care facilities here, or just researching later in life care if they are going to permanently stay here.

Live in a care home. It's all done for you. I worked in a school for five years and never did 90 day reporting myself. Our passports were collected by a Thai member of staff and taken immigration.

We need to form a welfare organisation for such situations and look after each other. I am helping a friend at present with the start of these issues.

If, when I get to that point in life and if I was still able I would get back to the UK, I've paid for the NHS for 50 yes working in a factory they can look after me,

One thing I found out. With a OA retirement visa, health insurance is mandatory. But most insurance companies drop you at a certain age, usually at 70. So you need to switch in time to an O retirement visa without a health insurance requirement. Furthermore, there are plenty of care homes that are affordable. I think you should arrange this and a good visa agent as soon as you feel the first signs that things are not going well.

This is something I think about as well

Its a worry saw one post recently where guy seems to have been abandoned by wife here and family back home. I guess authorities will contact embassy.

We are actually going to look into this after songkran see what living wills are possible in Thailand.

Do have one friend with severe dementia and his wife cares for him and also deals with the immigration.

I worry about this too.
