To understand what a Vietnam e-visa is, take a look at its features below: The E-visa is a single-entry visa. It will allow you to stay in the country for a maximum of 30 days.
Visitors who are holding an e-visa can stay in Vietnam for a maximum of 30 days or one month. Take note that this is a single-entry visa, which means you can use it to enter the country only once. You should be able to get out of the country before the 30-day period expires in order not to be slapped with a penalty. There is an option to extend the validity of your visa. You can look for an agency that can reapply for the visa extension on your behalf. Of course, this comes with a fee.
If you already know ahead of time that you will be staying in Vietnam for more than 30 days, you might as well choose a different visa option. For instance, you can apply for the Vietnam Visa on Arrival that will let you stay in the country for 90 days. You can even choose a multiple-entry visa for this option. But the only downside with this visa is that you will have to queue at the airport when you arrive in Vietnam.
No, you can only enter in Vietnam within the date specified on your e-visa. If you come earlier than that, you will be denied entry to the country.
You need to contact Vietnam immigration immediately as soon as you have noticed a mistake on your e-visa application. That way, they can rectify your visa and avoid any issues when entering the country.
Each individual traveler should have his or her own e-visa copy when entering Vietnam. Therefore, you cannot apply for multiple travelers in one e-visa application.
What if I realized that I made a mistake on my visa application and I have already submitted it? Send an email as soon as possible. They will be able to correct whatever mistake you have entered so you will not get into trouble when entering Vietnam using the e-visa.
