I am an American Citizen with a NON-IMM O-A Visa issued from the Los Angeles Thai Consulate on March 21st 2019 with an expiration of March 20th 2020. Is it still possible to enter a day or 2 before it expires and get stamped in for an additional year, then go to immigration in Jomtien and get a multiple-entry permit so I can use if for that second year? All this WITHOUT insurance? Or, is it now the case that the Visa will no longer be valid without insurance as of it's expiration date of March 20th 2020? Thanks!
