Could you not ask for a 60 day extension due to looking after a half Thai child. That will give you the seasoned time you need and then you can ask for a one year extension.
same thing happened to me, I didn't get an e-mail. I applied online 4 days before the due date. It came up pending, a day after the due date it was still showing pending. I phoned immigration, the officer checked the computer and said it's okay now. Shortly thereafter I got a confirmation e-mail. This was the Kalasin office.
I forgot about my report and did it on the Friday when it was due on the Monday. It came back as they all do, Pending. On the Monday it was still showing pending, as it was Tuesday morning. Tuesday I phoned the immigration office, and asked about it. The officer said let me check the computer, he came back in about 3 minutes and said okay you've reported. A little while later I got an e-mail with the new form and new reporting date. This was the Kalasin Office.
On your online application did it say pending? If so give the immigration office a call on the 3rd and explain your situation and ask if they accepted your report. With luck they will accept it. Last week I noticed on Friday that my report was due the following Monday, it said application pending. I phoned them Tuesday and asked if it was accepted, he said let me check the computer, he came back and said yes. This was the Kalasin office.
This happens to me frequently, I phone the office and they look after it for me usually in a matter of a couple of hours. I have no need to go to the office, I just give them a call.
, Kalasin has a separate room for 90 reports. However at Kalason they automatically do a 90 report for you, but they add it on to the day you apply for the extension not onto the day your last report was due. They do the same for online reports, they add it on to the day you apply, not the day it is due.
1 PM, sounds like you will be the first after lunch, so it will probably be close to that time. You won't be backed up by a previous appointee. Then again maybe they give all their afternoon appointments 1 PM then it would be first come first served.
kalasin Immigration office does it automatically for you. I did my extension of stay December 27, my 90 day report was due January 18, but Kalasin IO automatically extended it to March 25, 2024.
