: I have read the post. The MFA is going to question what has changed for you to go from a work permit/visa to digital nomad. Did you have a job in Thailand that you no longer have, etc.? They might want to see something. In regard to proof of employment, you need a letter from your employer. If you are contractor, others have been required to submit letters from their clients. In your case, I assume that would be letters from your students. Depending on where you apply, you might need to show tax invoices.
