It is my understanding that entering Thailand on an ED visa is dependent of whether it is for formal education or informal education - with the latter being excluded from the possibility of obtaining a Certificate of Entry at this point. Would a Thai language course offered by / in association with universities (as formal education institutions) currently allow for obtaining a CoE into Thailand? Any links to respective programs? Thanks.

Imagine someone arrived in the country on their initial 90 days Non-Immigrant-B visa based on a job offer (with Pre-Work Permit WP3) and then never started their job and never got their actual work permit within those initial 90 days. What are their options of extending their stay in Thailand beyond those 90 days without needing to exiting the country for doing so?

Can the initial 90 day Non-Immigrant-B visa be extended (similar to the way a tourist visa TR or visa waiver could in the old pre COVID-19 days), say for additional 30 or (ideally another) 90 days? So that they would still be on Non-Immigrant-B visa status, still able to start their job / get a work permit even after the initial 90 days have passed? (Preferred solution).

Can the initial 90 day Non-Immigrant-B visa be changed (status alteration) into a Tourist Visa TR, so that the visa holders could remain in the country for an additional 60 or 90 days after their initial 90 day period on the Non-Immigrant-B visa is over?

Can the initial 90 day Non-Immigrant-B visa be changed (status alteration) into an Education Visa ED with a non-formal institution (e.g. language school), so that the visa holders could remain in the country for an additional 3, 6 or 9 month after their initial 90 day period on the Non-Immigrant-B visa is over?

Any other possibilities for non-married persons without children and under the age of 50?
