I arrived yesterday in Thailand and got the 30 days stamp (German Citizen)
Can I go now already to the immigration office to extend by 30 days more (to have 60 days in total) or do I have to do that just before I have to leave the country.
If I do it now, do I get the full 60 days in total or will it be the days I have used from my 30 days entry stamp +30 days?
TLDR : Answer Summary
A German citizen who just arrived in Thailand on a 30-day entry stamp can apply for a 30-day extension at a local immigration office, including immediately after arrival. While some offices may have specific regulations, many allow extensions at any time during the 30 days, meaning the full 60 days can be obtained without losing any days. However, it's advisable to check local immigration office rules as practices may vary, particularly in certain locations.
