Is it possible to extend a 30 day tourist visa for 30 days when the passport will has just gone under the 6 month until expiry?
I know this can be a problem when leaving a country, but is it a problem for extending a short time?
Thanks for your advice :-)
TLDR : Answer Summary
You can extend a 30-day tourist visa in Thailand even if your passport has less than 6 months remaining until expiry. While there are concerns regarding passport validity when entering or exiting certain countries, extending a visa in this situation is generally possible.
