I am in the process of getting my visa extension for another 60 days due to COVID-19.
Just sharing with you all, what the immigration officer just told me. This is going to be the last extension, after this 60 days you have to fly out of Thailand, if not change your visa to marriage visa.
Furthermore fellow Singaporean, I had tried a few times talking to the embassy to issue a letter for me. They had been telling me the embassy does not issue such letter.
Today according to immigration officer, Singapore embassy issue letter now. Therefore go get your letter before heading down to MTT for your extension
