Can I pursue my research in Thailand on a tourist visa and later convert it to a Non-immigrant B visa?

An individual planning to conduct research in Thailand expressed a need to understand visa options. Specifically, they inquired if it's possible to go to Thailand on a tourist visa and later convert to a Non-Immigrant B visa after securing a job. It was explained that the ability to convert from a tourist visa to a Non-Immigrant B visa depends on the employer's willingness to handle the necessary paperwork, with the alternative being applying from a Thai embassy outside the country.
