– Question 10: Name, address of office, organization or full name, relation, address of your relatives to contact or visit ( in this case you can fill in your hotel name and its address instead)
– Question 13: Done at…(regards to where you fill in this form)
Note: Below the form indicates you need to submit 2 forms. However, this information is not exact as what it says. In fact, you only need to fill in one form and submit one to customs officer at Vietnam airport.
