The only issue with Vietnam's tourism is visa approval time

"Me as a European and as a traveler I say the only issue with Vietnam is the 5 days approval time for visa. I live in Kuala Lumpur now, if suddenly I want to go somewhere in ASEAN I’d go to Thailand or other places with no visa, cannot wait 5 days for a visa, at least make it instant approval like Indonesia."

"If you cross land border for visa run, it's 12 days, because they update after 5 days that you leave country. I have nothing against Vietnam, I live here 4 years, but 21st century still on the way."

"Visa fee is too high. Tourists are ready to spend over there. In that case visa fee [should] be waived like Malaysia and Thailand."

"The snowbirds who come to Thailand to escape the northern winter can now/soon get 60 days visa exemption plus another 30 days for 1900 baht. Many would like to do a side trip to Vietnam but after tackling the Vietnam visa website, find it frustrating so give up and travel elsewhere."

"There are a lot of things going on, rubbish everywhere and plastic bags everywhere you go in Vietnam, dangerous motorbike rider's riding on footpaths, red lights mean go faster, pedestrian crossings are a waste of white paint, no wonder people don't come back."

"Just make visa exempt for high-income countries and make public roads free of rubbish. Vietnam image will be improved 10x easy!"
