Vietnam E-Visa: Documents, Duration, and Application Steps

You need Passport valid for at least 6 months, JPEG scan of bio page, passport photo (4x6cm white background no glasses), international payment card, and confirmed Address in Vietnam. Application goes through official Portal, takes about 3 working days, costs USD 25 for single-entry or USD 50 for multiple-entry. You get up to 90 days but cannot extend it in country, must exit and reapply. If you overstay, you pay fine at exit calculated per day and risk Re-Entry Ban, so better report to local Immigration Office if you lose track of dates.
