Travel

Ho Chi Minh City port (SGN) is one of the best port to travel to Japan, Korea, Thailand, or Singapore, etc.
If you choose to stop by Japan or Korea on the way, I would recommend to can get 1 way ticket to Japan/Korea -> then to Vietnam → then from Vietnam to ATL/US.
If you choose to flight to other closeby Southeast Asian countries or around Vietnam, I would recommend to get tickets from Hochiminh City (SGN) to close-by countries which are around 2-hour flight (Thailand or Singapore). Or, explore other local cities such as Danang, Hanoi, Quy Nhon, Nha Trang, Da Lat. They are all between 1 to 2 hours.
EXPRESS AIRPORT PICK-UP service is available for $20 per person and it will take you through custom quickly. Let me know if you want it and give me your arrival details.
