How can I get a 90-day non-immigrant business visa for Thailand as a Dutch citizen starting a business?

A Netherlands citizen seeking a 90-day non-immigrant business visa for Thailand must prepare specific documentation, including proof of sufficient funding and an invitation letter from a Thai citizen or business. It is also important to have legitimate business documents demonstrating the legality of the business in Thailand. Instead of hotel reservations, a one-year condominium reservation can be provided. Applicants should verify the requirements of the Thai Embassy where they will submit their application.
