How often can I use a visa on arrival for Thailand if I am a German passport holder?

A German passport holder can enter Thailand using a visa on arrival, which allows for a stay of up to 30 days. Generally, there is no specific limit to how often you can enter Thailand within a year using this visa type, as long as you comply with the entry rules. However, frequent short trips using a visa on arrival could raise suspicions with immigration, potentially leading to more scrutiny during future entries.
