Can I cancel my visa extension in Jomtien after leaving my job in Saraburi?

If you leave your job in Saraburi, you must cancel your Extension of Stay at the Immigration Office in Saraburi where it was issued. This is required, especially if your extension is based on your working status. If you cannot leave the country immediately, you have the option to apply for a new Extension of Stay, but you will be given a time period to leave the country. Changing your visa details must be done in the region where your current address is registered.
