Dear members -- is Chamchuri Sq. 18th floor the correct place to go to get a 7 day extension on a 30 day entry stamp? I searched the forum but came up empty handed. What paperwork is required (photos, ticket, etc)? Is this extension granted "automatically" or is it at the officer's discretion? If i understand correctly, i go to Samyan MRT station and take exit #2?

Thank you.

I believe this is the One-Stop-Shop and is therefore only for those coming under the BoI rules. Normal visitors must go to the Chaeng Wattana immigration offices.

Per above, that is the One Stop Service Center and can only be used if othe company you work for falls under the BOI.

All other mortals must go to Chaeng Wattana Road: http://bangkok.immigration.go.th/en/location1.html

It is at the officers descretion, do take proof with you that you will leave the country within 7 days. They often ask for that.

I just had my stamps moved at one stop, no mention of working in a BOI zone.
