Which e-visa dates should I enter in Vietnam’s online arrival declaration when the issue date differs from the validity start date?

The issue occurred while completing an arrival declaration for Ho Chi Minh City: the e-visa was issued on 25 August but became valid on 3 September. The website would not accept 3 September as the visa issue date because it treated it as a future date.

When the actual issuance date, 25 August, was entered, the traveler said the form then would not accept the e-visa expiry date. This appears to be a form limitation when the visa issuance date and validity start date differ.

No verified workaround was provided in the discussion. Before submitting, check the e-visa fields separately for its issuance date and validity period; if the error remains, confirm the procedure with the airline or Vietnamese immigration authorities.
