Thank you all for your expertise and comments. I guess I will try it again online. Otherwise I just have to go there in person and hopefully afterwards I can do it online.
, thanks for your reply. I entered Thailand last year (2022) in August with a Non-O Visa. Once I was here I applied for a one year Thai Wife Visa and also the Re-Entry Permit. Both got accepted and is valid until 01.11.23. I also got a note in my passport that I have to make a notification on 07.01. if I stay for over 90 days in the kingdom. This is what i tried to do(tm47) and it got rejected. I was within the two weeks window. So I just wonder if there might be some reason for it (e.g. first time for this notification,...). Any advice or experience is welcome :)
