Is this number jail time

[Noodles]

I have this stamp B29 on 07 2002

and again in 02 2003 and 03 2003.

Do immigration change these stamps every

few months or is one officer allocated a stamp

for as long as he is in that office?

I have gone back to my country since these dates

applied for a 60 day tourist visa, have been accepted,

and have applied for 30 days extra at my local immigration office. No problems. Now I have to leave the country to get a

stamp. Are problems going to start now. Surley when

leaving thailand and then when re-entering if anything was dodgy it would have showed up on there computers eg; unpaid overstays?
