HI. I’m traveling by air to Hanoi airport. But I cannot find the Hanoi airport in the drop down list in step 1 of your visa application form. What should I do? Thank you. Gatrick.
Be kindly informed that the Hanoi airport is the Noi Bai Airport. So, please put the Noi Bai Airport as your arrival airport in your visa application form at Vietnamvisa.sg.
