Less than 5 hours after I passed through Immigration on my return to Bangkok last Monday, I went to my online account to fill in the TM30. Since there was no "Submit" button, I hit "Save", but my information seems to have been erased. I then reentered my information and, since there was still no "Submit" button, I hit "Save" again, with the same result that my information seems to have been erased. I don't know if hitting the "Save" button resulted in the submission of the online form, or whether my efforts proved to be for naught. In any case, I have not heard anything from Immigration by snail mail or email. Thoughts?
