I am about to do my 2nd visa extension in a row at the same office, and 3 overall within a year. Is there a limit to the extensions you can do?

I read on a thread here recently someone was denied, and that is because you can only do 4 within a year or something? Even if that were the case, I am still fine, as this will be my 4th overall extension.... but still, can you keep extending at the same location with no problems or will they eventually start questioning you more? I think the 1,900 baht you have to pay should make them worry less ....... it's not like extending a visa is free.

I cannot recall a report of anybody that qualified for the extension being denied. There is certainly no limit on them.

thanks!
