stating that it is always at discretion of the IO visa or not visa. but why an entry shouldn’t be allowed when you are using the correct visa and all the requirements are in place?
i don’t live in Thailand but come very often. Every 3 months i apply for visa, at my first entry i buy the multiple entry at the airport when leaving and repeat the process every 3 months. It might be costly due to the re entry cost but hassles free so i don’t mind spend more
yes, same documents for every application (excluding bank statements that need to be updated every month) and everything done trough your laptop in 5 minutes
tourist visa in case they are tourist METV in case they are frequent travelers as tourist. Or any other visa that qualify their status. Even if only for 1-2 days at a certain point the IO will recommend to get a visa.
