How far in advance can I apply for a Vietnam e-visa, and is 3 months too early?

You can apply well ahead of your trip. When you apply, you choose the date your e-visa starts, and the visa is valid only from that date, for up to 90 days. Applying 3 months early is fine as long as the dates are right and your passport stays valid.

A practical window is 2 to 8 weeks before travel. That leaves time to fix a mistake and lets you book hotels with the address you used. Applying too early has one risk: if your plans change, you may need a new application, which means another fee.

Do not wait until the last week. Immigration decides in about 3 working days by law, but delays happen around holidays. If you are short of time, look at urgent e-visa options before you fly.

You can check the rules on evisa.gov.vn before you apply.
