Extending Non O Visa

[rgs2001uk]

help reqiured please,

i went to immigration soi suan plu bkk yesterday, spoke to an officer in room 101, my extension of 3 month non o visa expires next month and i need to extend again.

asked the officer what paperwork i would need to bring with me when i make my application.

apart from the obvious, marriage certificate, house book etc etc she also told me of something i have never heard of, or seen mentioned in this forum.

something called , nangsu rap rong jaak.

it was only after i had left the building and was reading what the officer had written in thai, i realized i didnt know what this meant, too late to go back, office closed, that will teach me.

my wife cant help me either, and i wasnt asked for it when i made my last extension, is this some new reqiurment, or a case of the officer not understanding what is reqiured.

any help will be greatly appreciated by those out there who can please let me know what this means.
