mine was due today but I submitted it exactly 14 days before at 8 am . I was giving up but it finally got approved on this past Wednesday (considering last week Friday immigration was closed). I was planning to go next week -since Monday is a Publix holiday and I would never go a day before or after a long weekend. It was slow but I now set reminders to suit exactly the earliest possible to give it time. Best of luck
Same thing happened to me—-mine was due on the 12 and i submitter before April 6 holiday was still pending. On Tuesday got an am message said was received and by night time it was reject so I went yesterday on the 7th day to chanwattana to do in person and it was jammed pack with people doing their 90 days. I counted 12 people who had missed their date and had to pay the 2000 baht fine.
