I will fly to Saigon, Ho Chi Min first weekend of April to get a tourist visa in Saigon, travel the country for a week and return before Songkran. I have an appointement for Tourist Visa at Saigon early April, which you need to book IN ADVANCE, When I made the appointement in mid March that month of March was allready fully booked, so people might need to book about 2 weeks in advance. Just showing up at that consulate is NOT possible.
