That's only half true, the law has been passed but not yet in force. As already described. For this reason....
And this applies to ALL LAWS in Thailand. But it's actually like that almost all over the world. When a parliament decides something, it must first be published in the law sheets before it can be passed
Any adopted change will only become legally effective when it is published in the Royal Thai Gouvernment Gazette. This always appears on Thursday. This means that even if something is decided and launched, it is always serious after publication.
Even the question about work based on donations shows that you are actually informed about the legal situation.It is therefore not entirely clear to me what answers you expect here. Ideally, you should find out about the consequences if you are caught and reconsider your plans without work visa to offer services. And of course donations are also a paid service.
Your hotel, landlord or host must register with immigration. All within 24 hours. That would be the right thing to do, and I'm sure many people will write again and do it not. But that is the law.
Then tell it like it is, it can't be a problem.and report it to Immi through your girlfriend when you get there. Private individuals also have to do the TM30.
Idea in which country you are applying for your TR60. But with the online visa you will be asked why you are traveling to Thailand (visiting friends/family). and you have to upload your friend's invitation letter (with address and ID card).So there is no reason to be asked when entering the country because everything is already known. But don't forget to report to immigration within 24 hours of entry (TM30).
