@Nongnuch *******
it happened once with me that i didnt have the tm30 and i had no clue what was that doc , they asked me to bring my landlord with me to immigration and the officer told me something like tell her that he is asking her to come or he will go to her , once i told her she was terrified and i helped her out by doing it in another province cuz i was leaving any way and got my new tm30 from the hotel there
