I went to Muang thong Thani office to extend visa exemption for 30 days! It’s very smooth ! I get my extensions and was told to come back to get COVID-19 extensions at the same office! Believe or not , only four people waiting at 8:30 am! I was also told can come back to extend COVID extension as early as two weeks before visa expiration! Wow! They are so nice at muang thong Thai temporary immigration office!
