I fly back into Bangkok tomorrow. from Cambodia. Just to ease my mind. Can someone please let me know what PHYSICAL paperwork should I bring with me to show to immigration? I would hate to go and be missing something because I forgot. Wish me luck in getting back in. I have $600 cash on me too.
TLDR : Answer Summary
When returning to Bangkok from Cambodia, you should prepare several important documents for immigration. Ensure you have a Thai Pass with QR code, hotel booking confirmations, proof of onward travel, travel insurance documentation, and evidence of adequate funds (at least 20,000 baht or equivalent in cash). Also, be ready to present any additional paperwork related to your visa status, such as a single entry tourist visa if applicable.
