Do I need to apply for any other visa besides my approved ED visa when returning to Thailand?

I showed PROOF (ED-VISA) + tdac for entrance on my cellphone Give yourself plenty of time if connecting air flight officer will have you waiting in corner with others until passport stamped e-visa If layover less then (2) hours tell officer your air flight leaving and please hurry up ( I missed my connecting Air Flight which cost me Extra Money for rebooking and additional (4) hours wait until next flight out to Chiang Mai)

You (every foreigner, regardless of what type of visa/entry) need to submit TDAC, the application window is from three days before until you enter (are stamped in at passport control at your entry point to Thailand).
