What are the options for Brazilian expats to live in Thailand legally for one year while working remotely?

Start by reading the visa section of the Thai Embassy website in your country.

You can consider the tourist visa, which usually allows a stay of up to 60 days, with the possibility of an extension. Another option would be the non-immigrant visa, which offers more flexibility. Some student visas require in-person classes, but you can look for schools that offer courses with more flexible requirements. There's also the digital nomad visa, ideal for those working remotely, which could be a good option for you.

I recommend reaching out to Expat Money Forum, which can help you understand the best visa options and processes for living in Thailand legally.

For remote work you really only have the DTV option unless your wealthy enough and the company you work for qualifies you to get the LTR visa. You can't work on an ED visa which is for studying

You can always take classes at a University that are for English majors.

Look up the DTV visa. It has a remote worker category.
