What are the steps for a Thai citizen to obtain a passport?

The process of obtaining a Thai passport for a Thai citizen is generally straightforward and can typically be handled independently by the individual. Steps generally involve going to a passport office with necessary documentation, such as an ID card, and possibly a few passport-sized photos. Many commenters suggest that these offices are easily accessible in places such as shopping malls (e.g., MBK in Bangkok or Central Festival in Pattaya) and that the process can take as little as three days. Some community members emphasized that if the girlfriend is Thai, she should be able to find the required information online or through local resources without needing assistance, suggesting that the question posed could be seen as unnecessary.
