The fact that your actual port of entry does not match the one you declared on your Vietnam eVisa application generally does not cause a major problem, as long as you still enter Vietnam through an international checkpoint that is eligible for eVisa use.

Vietnam’s official eVisa portal clearly states that eVisa holders must enter and exit Vietnam through international checkpoints authorized by the Government.

Vietnamese representative offices have also noted that the actual port of entry does not necessarily have to exactly match the one selected when applying for the eVisa.

Therefore, you may enter Vietnam through any eligible port of entry without needing to worry too much about the port you originally declared, since the port of entry is not shown on the eVisa itself.
