He will have to pay a 20k baht fine on exit AND will be banned 1yr at 90 days.

If he were found by police on the street, for any reason, it's detention, deportation and min 5 yrs.

Hospitals have departments that help with these requirements.

It is too late for any medical extension relief.

Sir you have joined a Visa Advice Forum.

Your choice of visa, based on your idea is not the best path for you, based on your requirements.

The advice given is correct and the best path for most applicants.

The required insurance becomes problematic, especially as we age.

The non-o allows the use of any suitable insurance, tailored to your needs.

If your intention is to stay then the OA multientry 1yr visa, will work but is NOT your best path.

You will still need the money in Thailand in both cases for ectension and 90 day reporting is just a fact of life.

However choose your own path.

@Tom ******

you could apply for the 60 day visit Thai family extension as long as you've not done one before.

If the money was out and then in on the same date it shouldn't be a problem.

It will depend on the office and officer you are in front of.

As per

@Bra****

in short.

Go to your local immigration and get the information on 1yr extension.

Get the 400k in your bank.

Then when you are near the end of the 90 day visa, apply for a 60 day visit Thai family extension, giving your money the time to season before the 1yr extension.

This really is the only path available other than maybe the agent route.

Which is problematic in the long run.

ALMOST ALL available cheap OTC

The list of documents is substantial and a small company without experience may not be able to provide all.

Whether they or you pays an agent, that's up to you.

But if you are unable to provide the documents you will need to leave and start again or end up overstay till you do.

At 500b per day and an ugly stamp.

The simple answer is:

Only if you have a Thai bank account and 400k in it AND still have time left on your entry stamp, usually at least 15 days.
