Do I need a visa?

Hello. Im from CHILE and I'll be in Vietnam in 2 weeks so I need to know if a need visa.

I read this: " No visa is required for travel in Vietnam for less than 90 days or several visits within 6 months for citizens of Chile who holds valid diplomatic or official passports."

So I just need my passport? That sound GREAT but I need CONFIRMATION because I don't want any problem when I get there. Thank you.
