Dear Minette W,
Please inform that both South African and Myanmar passport holders are required for Vietnam visa. In case you travel to Vietnam by air, we recommend you to apply for Vietnam visa on arrival online in advance. Otherwise, if you enter the country by land or by ship, you are suggested to get your visa at the nearest Vietnam embassy/consulate where you are staying or living.
Should you have any further concerns about Vietnam visa information, please do not hesitate to contact us at anytime.
