Do I have to stay 2 days in Vientiane for a visa on arrival, or can I get it the same day?

Whether you need to stay in Vientiane for two days depends on the entry point you use for crossing into Laos. At the Nong Khai border, staying the same day typically allows you to get a visa exemption without additional delays. However, it's advised to use a reputable border run service to guarantee a smooth process. In some cases, the stay could extend up to three days.
