Hi there group. I am on 12mth Ed Visa, which requires regular 90 day extensions until the end of Nov 2018 when the year long language course ends. I’m planning to go back to Aus for Dec/Jan and have just spied cheap flights in first week of Dec - one week after my Visa is set to expire. Am I able to get an extension by doing a land crossing (at Mae Sai for example) so that I can fly a week later?
