According to the post, Thai customs typically fires off five main questions: First, how much cash you are carrying; second, your hotel reservation details; and third, your outbound flight ticket. They will then ask about your travel itinerary, requiring you to name at least three specific tourist destinations. Finally, they will ask about your occupation and request proof of employment.
The netizen strongly warned against using paid "VIP clearance" services. This operates as a grey-market industry at the airport. The hidden catch is that once you use it, your passport is flagged in the system across all major Thai airports. You automatically become a "long-term customer." The next time you enter, regardless of your visa type, a pop-up will appear on the officer's screen. If you don't pay for the clearance again, they will find an excuse to pull you into the office.
In reality, normal travelers do not need this service. The strictness of the questioning largely depends on how often you have entered Thailand in the past year. Regular tourists visiting once or twice a year have nothing to worry about, as they face minimal questioning, and passengers on some flights are not questioned at all.
