okay, let's get you sorted out,
you didn't arrive here visa test&go or thai pass <- those are things EVERYONE comin' in meets or doesn't get in and have nothing to do with the type of visa or lack of when you enter 😕
Also you didn't even on a visa on arrival 😮 That is something SOLD to people from 18 countries when they show up here for 2000baht for 15 days and cannot be extended
IF you showed up here without having bought a visa from a thai consulate in your country and were stamped in for FREE here for 30 days you got in on what's called a 30 day visa exempt entry.
To get the one 30 day regular extension of that in Bangkok you go to the new immigration office at IT Square Laksi Plaza at this location;
