I got a new passport after my e-visa was approved. Do I need to transfer the visa?

An e-visa is linked to the passport number you used on the application. If you get a new passport, the old passport number on the visa no longer matches the document you carry, and you should have the visa moved to the new passport.

Do it even if you leave soon. Immigration compares the visa with the passport at the border, and airlines check it at check-in. Sources that say it is not needed are risky, because a mismatch can lead to delays or refused boarding.

How to proceed depends on where you are. If you are in Vietnam, go to an Immigration Department office with both passports and your visa, and ask for the transfer. If you are outside Vietnam and have not entered yet, apply for a new e-visa with the new passport.

Keep the old passport with the new one. If you need a new visa fast, apply for an e-visa with an urgent speed. VietnamVisa.com is a private visa agency, not a government website. You can apply yourself at evisa.gov.vn for US$25 (single entry) or US$50 (multiple entry).
