What should I expect when applying for a 30-day extension in Ko Samui?

Wanted to give an update on my 30 day extension experience at the immigration office in Ko Samui. It’s bit of a mad house if you go after lunch. I ended up waiting about an hour to have my number called to pay for my application then another half hour for my extension stamp. Bring a BLUE PEN or else you’ll be scrambling to borrow one. The shop downstairs next to the office offers printing services of 5 baht per copy if you need to make any. I don’t know how much the photo costs as I already had an extra one but they also offer this service. Inside the office, there are signs posted clearly stating you need to wear a mask and have proper attire, but it was not enforced by any Thai officials. People were wearing shorts, tanks, flip-flops, even saw a middle aged woman wearing daisy dukes 🤦🏻‍♂️ otherwise, process is very straightforward, just allocate spending about 2 hours of your day to get your extension
