How can I apply for a DTV visa in Thailand if I have a freelance contract and currently hold a business visa?

Hello hello

I want to apply for a dtv visa

The situation is: I live in the district of Surat Thani and have currently a business visa & work permit

My idea is to change it to a dtv visa this month (business visa comes to an end) and I got all the needed documents to apply for the new visa

My questions:

1: I have a work contract as a freelancer - which is kind of a contradiction. So did anyone apply for this visa with a freelance work contract already?

2: I want to apply in Malaysia for the visa, how long does the process usually take - did anyone apply in Malaysia in the last 2-3 months in Penang or Kota Baru?

3: is it in theorie possible to apply first in Thailand and only if the visa is granted to leave the country

4: is it a very different process and really recommend to get help for a visa agency?

Thanks in advance 🤟🙏
