I first went to Vietnam in 2014 for 3 months (April-June) then returned a few months later for another month. I just returned from Vietnam, again for three months. May/July. Will there be any difficulty reentering again in another month?
Dear Bryan Graham,
Thanks for your question,
we would like to inform that if your approval letter has valid you can use it to enter Vietnam in this period time.
However if it is expired, you have to apply for getting a new visa. please check at this link http://www.vietnam-evisa.org/apply-visa.html
Is case, if you have another problem please send it to our email firstname.lastname@example.org. we will check and reply for you.
