What is the process for a successful visa run from Cambodia to Thailand?

Overnight Cambodia "visa run" a success:

Can use same PCR test if the travel dates are within the 72 hours. Print 2 copies. Fit to fly certificate not required but doesn't hurt to have.

ATK test at Phnom Penh airport was easy but painful. The guy jammed the swab in my nose so far and rough I bled. He laughed.

Flew Thai Smile the next day back to BKK. They will check ALL Thai Pass required documents. If you are entering Thailand on a VOA or exemption she will ask to see the departure ticket from Thailand. She entered my departure ticket into the computer for verification.

Takes awhile for all this, so it helps to have everything printed and organized

Arrived in BKK:

Easy if you have all documents printed and organized

Immigration not busy at all. 15 minutes.

Exemption visa approval without checking bank statement or departure ticket but must show proof of address where staying. I have rental contract

Hotel rep will check your docs and call the taxi. Wait about 15 minutes.

A nice private sedan will pick you up and take you to the PCR test site then to hotel.

Taxi is fully shielded and sanitized.
