a border run requires wasting a whole day sitting in airports and on planes and is more expensive. An extension is cheap and only takes 1 or 2 hours at immigration if the documents immigration want are supplied
The extension is easy. It's the same documents you used for your application with updated dates, plus proof of where you are staying.
An extension is faster and cheaper.
Why would you want to waste a whole day sitting in Airports and planes and spending more money when all you have to do is spend an hour or two in the evening printing out documents and then the next day going to the immigration office for maybe a couple of hours....
Yeah its a good option. It's very cheap as well. To stay 6 months that will be 2 x extensions and 1 border run.
3800 baht for the 2 extensions and use a land border run company it's between 3000-4500 baht depending which border.
So you are looking at about 8000 baht per 6 months stay with no issues.
If you can get a DTV for being a remote worker then it's your best option cause you only have a one off cost of 10,000-12,000 approx for the application fee.
If you need to use the soft power way then you will have to pay 10,000-12,000 for the application and also pay for a course which could be anywhere between 10,000-30,000+ baht.
