Hey folks, I went to KK Immigration for my "consideration" stamp follow up a few days ago (for SETV). The IO simply asked for my passport and nothing else. The whole process was rather quick and the immigration office was the emptiest I've probably ever seen it. When the IO returned my passport with the new date (April 28) I asked what I should do if the Covid situation is not cleared by then. She tried to explain in English, but eventually just handed me a paper with the English translation of the visa amnesty decree (ie. visa amnesty for persons whose visas expired from March 26th). She did not mention anything about returning to the office or bringing a new letter from the embassy.
It should also be noted that I saw her highlight my name off a long list. I'm assuming this was the Covid consideration list, hence I suggest that people with the consideration stamp do show up to their local immigration office or at the very least call them.
I really hope my interpretation of her actions is correct, otherwise I'm going to end up forking over quite a bit of over-stay money when I actually do fly out of Thailand. Looking forward to hearing about what others experienced.
