So, on Monday I did my TM30 report. Landlord haven't submitted anything into the system, so IO insisted I bring him in person ("Thai people should come we need to tell them about your visa"). But after I told them he is 79 years old they agreed if I just get his papers signed.
Tuesday, cancelled my extension of stay. Immigration officer who is dealing with Non-B visas said that because I overstayed in their province I should apply for 60 days covid extension there as well, doesn't matter where my TM30 has been filed. Paid the overstay fine, was sent to another counter to apply for "60 days", and immigration officer there said if I don't want to go back and forth after "under consideration" time it's better if I do 60 days and pay for overstay where my TM30 is. Alright then, refunded the overstay fine.
Today, succesfully applied for 60 days extension. Had to show things like electricity and water bills, because "Tambon" written in the Tabien Baan is different with what it should be in reality (house I rent is literally on the border between two Tambons, so thats where I guess someone from the Tambon Department made this crucial mistake). For today it was okay, but next time, I was told, they won't accept it - landlord have to fix it.
>You may need to formalize your cancelled extension of stay, if you don't have it actually cancelled yet. You'll have to go to Chonburi immigration.
Yes, it's not cancelled yet. But after I do this, where to apply for Covid extension? Am I correct it should be done at the IO where my address is registered?
