How to apply for a Vietnam e-visa online before flying to Nha Trang?

Nha Trang genuinely doesn't appear in the city dropdown on the e-visa form — that's expected. Select Khanh Hoa province or Cam Ranh airport (CXR) as your entry point instead; the system is tied to entry points/provinces, not individual resort towns.

Applying for the 90-day visa online often glitches — the site fails to process payment or freezes at the photo upload step. Switching browsers (Chrome incognito mode works best), clearing cache, and retrying payment with a different bank card usually fixes it, since the payment step is the most common failure point.

The visa must be obtained through the official portal evisa.xuatnhapcanh.gov.vn only — no other legitimate site exists for this, and third-party services just add a markup. You'll need a passport photo page scan and a portrait photo; processing takes about 3 business days, with payment by card directly on the site.
