I have been on an ED visa since 26 june 2021. My visa expires 26 june 2022. i'm leaving thailand 20 june 2022. 
 But the issue my tm47(notification of 90 days) is expiring on 6 june. The lady at the school said its ok they wouldn't bother me. But i wanted to ask here to make sure.
If i leave on 20 june would i be fined ? For 14 days not reporting.
Any answers would be highly appreciated
TLDR : Answer Summary
The user is concerned about fines for not reporting their TM47 (90-day notification) before leaving Thailand on an ED visa, which expires after their departure. Comments advise that as long as they are leaving the country, they may not face immediate fines, but should cancel their Extension of Stay to avoid issues upon a future return.
