this seems to be contrary to what you claim. Quote "One thing to keep in mind with respect to non-admission into the Kingdom is "finding a place to land" if you will. so those that come into Thailand and have been rebuffed from admission, not all jurisdictions are going to readily welcome that individual or those individuals into their jurisdiction because they sort of "red flag", for lack of better term, deportees; people that have been denied admission to a given country. So in some cases there may be no choice but to go back to one's home country and either get a new Visa or make other travel arrangements or maybe make no other travel arrangements because they may not be admitted or admissible back to the Kingdom at all.
That being stated, the thing to take away from this video, if you are denied entry, you will be generally speaking granted an opportunity to make further travel arrangements and go to another country. It has been my experience that people that are rebuffed entry here in the Kingdom oftentimes end up over in Cambodia, sometimes Malaysia. It is going to depend on the nationality of the individual involved as well as the reason for turning that individual away. If it is simply a matter of having too many tourist visas, some other jurisdiction again Malaysia, Cambodia, Vietnam will probably take that individual in although it is not a foregone conclusion and from there they can make they can make arrangements accordingly."
