What is the process for applying for a visa extension at the Pattaya Immigration office in January?

Applying for a visa extension at the Pattaya Immigration office may require an additional follow-up visit after submitting the application. A recent experience highlighted that after picking up and filling out the application form, an applicant was instructed to return on a specific date, in this case, January 20, to complete the process, which is considered standard protocol especially for extensions related to COVID.
