We are traveling from Cambodia to Vietnman by river cruise. Your site only talks about arrival by air or land, but not water. Should we obtain our visa while in the U.S. before starting our river cruise?
I will be visiting Vietnam in October and have visa approval letter for single entry visa upon arrival in Ho Chi Minh. Then I will be going to Cambodia for a tour. When I leave Siem Reap, I will be flying to Ho Chi Minh airport on Vietnam Airlines. I will change to Korean Air for my international flight to US. I will not be leaving the airport, only going to Korean Air for flight. Do I need another visa? What is this new transit visa from the government? THANK-YOU
