I guess you want my opinion as you use my name.
Keep going on mixing all to a giant coctail to keep a discussion going.
Why not keep to one subject without moving to all kind of other things.
What is the job description of an Immigration Offier and is the officer allowed to check the reasons an visa is issued before the officer stamps a passport with a certain period of time to be in Thailand. Can an Immigration Officer file the case to a court to get a visa void?
OR are you willing to discuss the terms and conditions of a visa, which is as you said, correct. You apply for a visa meeting the requirements and the visa stays valid until the day mentioned on the visa, OR getting void by court order OR getting cancelled by the visa holder.
What is next? the funds in a bank for an Extension of Stay?
