I asked for help recently as my landlady was unwilling to do the TM.30 report for me.
Someone suggested that I instead do the report myself online, which I did. However, doing my 90-day report in person today at Chaengwattana Immigration, I was asked to "redo the report" then and there. My online TM.30 was not accepted, I was informed that I, as the tennant, cannot do it, my report was cancelled, and I was fined. Considering time and money spent, I wish I had not done either report, as the expense would have been about the same, but no stress, and time wasted.
