I have a question about the TAX in the wiki...
To be exempt from this 18% tax (IVA), a guest must present both a valid, original passport and a copy of an immigration card. Guests who are unable to present both documents will be required to pay the tax.
I am citizen, born and raised in the USA, I only have a USA Passport, what exactly is "an immigration card". I know what a green card is, but why would I need that? Can anyone answer this?
Thanks
