What are the recent challenges faced at Krabi Immigration for the Extension of Stay application for retirees?

No matter what people say there is a definite appeals process IF you don't agree with an immigration office or officer's decision or what they're telling you. )

It takes you putting on your big boy pants and standing up to some pretentious official in a too-tight of government uniform BUT it can be done.

Legally If they are going to deny an extension application they have to give you a written denial outlining why you were not approved, they have to give you a written list of things to do that will get you approved AND they have to quote the actual immigration order, clause and sub-clause that you were denied for not following.

The thing is most foreigners here have abysmal thai skills (meaning they can barely string 3 thai words together in a semi-coherent sentence) and most immigration officers have equally abysmal engrish.

OR the foreigner goes to the immigration office with their thai signficant other (one who is sh*t scared of any thai in a uniform, doesn't know their ass from their elbow about immigration rules and is too afraid to argue with an officer who is telling you something that is incorrect). This can and does lead to problems..

All I can say is that I've filed appeals on quite a few decisions that I felt were bad from the initial immigration officer (actually in several different immigration offices back when I used to do "field trips") and gotten every one of the denials overturned on appeal. I wasn't doing anything but compelling the office to actually follow the rules as they're posted, not as they're pulled out of some power-tripping officer's backside :O

Good Luck to one and all.
