the 800k must be untouched for 3 months after the application. Does that mean the balance must stay above 800k all the time, or that you are just not allowed to use the account?
If you need to apply in a small immigration office, it's very likely you'll always meet the same person doing your extension. Go to talk to them. Officially you visa ends on the day you graduate, but they might be not too strict about it. That said, the real issue is probably if you can change an education extension to a non-immigrant-O visa based on marriage.

. Just go on the first working day starting from your appointment date. Approval typically happens near the deadline. No reason to go early.
Having the father of my ex speak out for me helped me enormously. He and the immigration officer could find a solution for me. In cases like yours individual decisions of the officer are important.
@robert lagas It happened before corona, but I remembered it because the lady had to pay 800 for each person. And I believe she had 5 guests that needed other paperwork too. The officer said that someone needed to pay the fines in order to make the registration. And without registration she could not apply for the other paperwork.
Thank you. I asked because were I live reporting online is the safest option. Last time I went to report in person, there was a Thai home owner that wanted to report Cambodian workers that came to live in her house, but she was fined because the previously home or hotel owner failed to report. There was no record of these people in the system, and they were already a few months in Thailand. They wouldn't give her the necessary documents unless she paid for the fine caused by the previous home/hotel owner.
