I have a question regarding 90-day reporting. I've trawled through the site but can't see an answer. I am here on an O-A visa which I obtained in my home country. Stamped into Thailand on 21 January 2019. My residence is in Phuket. So...I need to report around April 15th to Phuket Immigration? What if I am away in say, Khon Kaen at this time? Can I report up there, can I report online? Thank you in advance.
