I entered Thailand at Mukdahan on a 90-day single-entry non-O visa based on marriage obtained at Savannakhet on 14 Nov 2019 and was stamped in until 11 Feb 2020. Yesterday I applied for a one-year extension of stay based on marriage at Roi Et and the under-consideration-of-extension-of-stay stamp instructs me to return to the immigration office on 12 Mar 2020. My understanding is that I cannot leave the country during the "under-consideration" period so I assume that stamp also implies permission to stay until 12 Mar 2020. Is that correct?
I also assume I need to do the 90-day report on or about 11 Feb 2020. Correct?
