Which immigration office in Bangkok should I visit for the letter of residence to renew my driving license, and can I get it the same day?

To obtain the letter of residence required for renewing a driving license in Bangkok, you should visit the Chaeng Wattana immigration office. While some users mentioned that they may mail it to you, others indicated that if you visit the immigration office in the morning, you could potentially receive the letter on the same day. Additionally, it’s important to have completed your 90-day report as it is one of the requirements for obtaining the letter.
