First of all you should have an option for 1 language AND an option for 2 languages separately there's a big difference between the two.
I also assume you mean fluently and if so I can read/write/speak English and Portuguese. I also have dual-citizenship in Brazil and the USA.
If you mean speak the basics I would add in Spanish and French.
Took two years of French which is similar to Portuguese in a way and I live in the Hispanic-Dominated Central Florida region. Oh I also work at a McDonalds comprised mostly of Latino workers.
I voted 2 but I guess I could vote 4 depending on your standards.
