Promptly and conscientiously
Hi , in the application for my visa I choose a date of arrival, but I’m arriving before that date. Is that a problem?
Please be informed that you can arrive in Vietnam later than your granted arrival date but you CANNOT arrive in Vietnam before that date. If you wish to travel to Vietnam before that date, you are highly recommended to apply for a new visa to Vietnam.
I hope this information is clear to you. Should you need any further information, please feel free to contact me.
