Let's assume an EU citizen who is entering by air to Laos with a valid passport. Is he required to have a return ticket already booked to obtain the visa on arrival when arriving to VTE (Vientiane) airport?
From the information I find online, none mentions that but since I cannot find any information directly from Laos authorities, I would like to double check it. The reason is that in many countries the visa on arrival is only granted if a return ticket is available. In some even you cannot check in if you do not hold the return ticket.
