Do I need to enter the exact arrival date on the application form or could i put an estimated date since we are unsure of the number of days we wish to stay in Hong Kong yet.
Once we submit the application online, is there anything else we need to do afterward?? What do we need to bring along with us to show the border guard at the Vietnam international airport that we have applied for the visa to enter the country??? In addition, do we need to take visa/passport pictures to present to the border guard???
Thank you very much for your help, I look forward to hear from you soon,
