Is there a way to pin an FAQ for immigration questions in Thailand?

The reason a FAQ or any pinned information is mostly useless for immigration matters is because everything is handled at the local level. There is no one answer that fits every situation, fits every immigration office, or fits every embassy. Each immigration office in every province of Thailand sets their own policies and requirements. Each Thai embassy overseas sets their own policies and requirements. And these change constantly as well, based on the leadership and staff at those locations. Any information would be outdated the week after it was posted.
