Congratulations! That is indeed very quick and thank you for sharing your experience with the community.
- Do print out your supporting documents especially your e-visa when coming into Thailand.
- Check your passport stamp when passing the immigration as there has been cases that the officer mistakenly uses the
*****
day visit visa instead of 180 days DTV stamp.
- Will be good to mentally prepare the small chance that they ask some questions about your intention in Thailand and how you will support yourself. It doesn't happen often but it's good to be prepared if it comes to that.
