Sure there is no obligation to give complete answers, but being rude to people who try to complete your answers is just not done.

I indeed have no idea about what you know, and I am not honestly interested in what you know.

If your answer is not coming from yourself it makes it even more ridiculous to post here as an incomplete answer.

I never claimed I am an expert or immigration lawyer, why should I.

Your comple answer is simly WRONG now, it is absolutely impossible to submit both applications at the same time, because on the dependant application you have to show proof of the DTV of the primary applicant, which you simply do not have until that one is approved.

But by now I know you are a very despicable and arrogant person.

@David *******

laminating and smaller size might make QR code less readable. You can check readability with your own phone.

On the other hand, why laminate as long as you also can print again when you need one.

@Sebastien **************

You said "primary applicant needs 500K" which might suggest the dependant applicant does not need 500K, I did not say your answer is not correct, it just might need some extra clarification.

@Sebastien **************

both need 500K, in some cases it is also accepted 1000K and sponsor letter. When you look at requirements for the three different types, you will see all three mention the 500K

I think a lot of people think they can use the visa legally for 5 years when they only have activities of 6 months.

Of course the visa is only valid as long as the purpose of stay still is valid.

The OP specified a planned longer treatment, for as long as that treatment lasts I think Thailand is happy, not everything needs to be highly specialistic.

I think the people only having a relative short soft power activity who after ther activity still coming illegally in Thailand will be maore a reason to axe this visa or to implement more checks.

@Alex ******

There is no leeway!

You are allowed to report afterwards for some days, but that does not mean you can stay over 90 days in a row without reporting.

Some immigration office might take time, some others it is within 5 minutes.

Preparation does not really take time, fill in an easy TM47 and make copies of TM30, passport and visa.

And you are right, only if you really want to travel you might travel outside every 90 days, but for preventing 90 days reporting that seems a bit overkill.

I would not plan my trips in such a way to prevent TM47 reports

I would ask the staffer to confirm this to you in an email.

@Patrick ****

This is a general rule for visa everywhere in the world, and a lot of Thai embassies also show it on their website.

@Sean *********

You apply for a visa somewhere without looking at their webpage to see how procedures and waiting time are?

1. Officially after the 15 lessons when you don't take lessons anymore you do not comply anymore with the visa requirements.

At the moment this is only checked when you extend in country for additional 180 days and very rare at (re)entry of the country.

It is up to you what risks you want to take.

2. if your application is granted and you have a marriage certificate, she can get her own visa as dependant from you, she also needs 500K in the bank, some embassies also accept 1000K in a joined account.

3. Also depends on embassy, some accept when the money is there at application date, others want it a number of months before.
