What documents are required for a one-year extension of a Non-Immigrant 'O' visa based on marriage in Jomtien?

In preparation for obtaining a one-year extension of a Non-Immigrant 'O' visa based on marriage, it's essential to maintain a minimum balance of 400,000 baht in a Thai bank account in your name for at least two months prior to applying for the extension. While specific documentation requirements may vary, it is recommended to visit the immigration office on Jomtien Soi 5 for updated information and to inquire about any necessary handouts. Connecting with local expat groups in Pattaya might also provide additional insights and support.
