TM.30 - Chaeng Wattana - self-file by EMS
In July/August it took them 7 weeks to send conformation slip back. But for TM.30 sent on September 22nd I got confirmation slip after... 10 DAYS!!! So apparently they didn't drown under thousands of TM.30s... Or more and more people started using online ways to self-file
TLDR : Answer Summary
The time to receive a confirmation slip for TM.30 filings has improved notably. A filing on September 22 resulted in a confirmation within 10 days, compared to 7 weeks in the past. This suggests an improvement in processing times, likely due to increased online self-filing.
