Can you apply for a Vietnam 90-day e-visa while already in Vietnam, or do you need to leave first?

For a visa run from Da Nang, Lao Bao border crossing is an option. One offer priced round-trip transport plus the 90-day e-visa process at 2,700,000 VND per person; it reported approval about an hour after submitting the required details.

Applying for a 90-day Vietnam e-visa while physically inside the country is not possible — this is widely confirmed by travelers. You must exit Vietnam first.

The standard approach is a 'visa run': leave Vietnam, apply for the 90-day e-visa from outside the country, wait for approval, then re-enter. A simpler alternative is a 'border run' — exit and immediately re-enter to get a new 45-day stamp.

Laos is a popular destination for a visa run from Da Nang. You can travel there, submit the e-visa application online, and return to Vietnam once it's approved.

If traveling with an adult child, each person must apply for the e-visa separately — there is no option to link applications as a family. Each adult submits their own individual application.

A minor child can be included in a parent's e-visa application. An adult child (18+) must apply separately on their own.
