Do a French citizen need Visa for 1 month staying?

Dear Sir/Madam,

French citizens need to apply visa for a stay of 1 month, you can apply with us through our website https://www.vietnam-evisa.org/apply-visa.html. You only need to fill in the form then pay online. After 2 working days (for tourist visa), we will send you the approval letter via email, you just print it out to board the plane and use it to get visa stamp at Vietnam int’l airport. Base on your trip, you can apply the tourist visa for 1 month single entry with the service fee (19USD/pax paid online) and the stamping fee (25USD/pax paid in cash at Vietnam int’l airport).

Best Regards,

Eve Du (Ms.)
