Holders of a Thailand Privilege Visa may still need to present themselves in-person to the Thai Immigration Authorities:

• To complete their mandatory 90-day reporting every 3 months.* This is required in person only the first time. Subsequent reports can be done online.
• If members do not wish to leave at the end of the full year and want to stay a few extra days, they will need to visit the immigration office to request an extension.

* NOTE: Members can appoint an agent to report on their behalf for free, granting a pass from having to present themselves in-person. However, attending immigration in-person is also an option.

For the above, you can head over to the Thai Immigration Bureau (Immigration Division 1: Government Complex) on Chaengwattana Road to meet with a Thai immigration officer. 

Other visa holders may need to visit immigration to extend or renew their visa. With a Thailand Privilege Visa, members only need to visit the airport every 5 years to renew the visas they were entitled to as part of their membership. Once they have stayed in Thailand for a full year, they can reset the clock by leaving the country and re-entering the next to get their stamp at the airport, no re-entry permits required.
