Can be done but you need correct paperwork and approach. Be polite and if they don't understand ask for manager. Ask them to set up the app also so you can pay bills and purchase food and foods. Say you want to transfer money from your country every month. Be patient and don't give up
Don't listen to rumors. You can actually ask immagration anything you don't understand. They are not the enemy you have been issued a visa to stay if you ask a question they won't ask you to leave. Seriously go to the source not some farang who doesn't know
and when people start doing extensions they will post here. So it won't be rumor. Of course it won't be an official announcement I didn't say that you did
Correct that is the way this visa is set by immagration. Apply outside 180 days on entry + 180 days extension in Thailand. Then border bounce start again continue this process for 5 years. But there has been no feedback from anyone who has done it yet as the visa is under the 6 months but should start to see comments of people who have done it. Only rumors and guessing at this point
