Dong Hoi is the primary access point to Quang Binh province in Central Vietnam, a region renowned for its significant natural landscapes and historical sites, notably the internationally acclaimed Phong Nha-Ke Bang National Park. The process of entering a foreign country, particularly following an extended period of travel, can present certain complexities.

Waiting in lines at the immigration checkpoint in Dong Hoi International Airport can be exhausting, especially after a long flight. With limited staff and high passenger volumes during peak hours, queues often stretch for 30–60 minutes.
