The national flag carrier has completed all necessary documents to be approved by the U.S. Transportation Security Administration (TSA), it stated.
It is set to receive the permit from Federal Aviation Administration (FAA) soon. The airline did not specify a date.
Vietnam Airlines said the permit is different from that given earlier for international special charter flights between Vietnam and the U.S.
The carrier had earlier received permits to conduct 12 charter flights last year and another 12 this year.
Bamboo Airways had also received a permit to fly 12 charter flights to the U.S. from this month to November.
Last month, Bloomberg reported Vietnam Airlines was planning to operate regular flights between Vietnam and the U.S. starting October.
The airline in 2003 was ordered by the Ministry of Transport to begin direct services to the U.S. by 2005. However, concerns about profitability kept the carrier from realizing the goal until now.
