Can I extend my tourist visa in Thailand with a one-night hotel booking if I plan to stay with friends?

When applying for a tourist visa extension in Thailand, it's important to note that the immigration office requires proof of accommodation, such as a hotel booking. In this case, a one-night booking for the day of the extension should suffice. However, if you plan to stay with friends, they must register your stay with immigration, typically through the TM30 form, which is a notification of your residence.
