When can I apply for a visa extension in Chonburi Pattaya after a 30-day visa exempt entry?

In Chonburi (Pattaya), you can apply for a visa extension only during the last week of your existing 30-day visa exempt entry. It's important to wait until this time to avoid wasting your time at the immigration office. You will need to provide a TM30 receipt from your hotel when applying for the extension. Additionally, it's suggested to arrive early at the immigration office, possibly during the week prior to your stamped ending date to ensure your application is processed smoothly.
