Does the Aruban immigration department require other paperwork besides a passport? I know some countries ask for a round trip ticket, proof that you have the money to finance your stay, proof of accommodations etc.
You need pretty much all of those things. Passport/visa and an Embarkation and Disembarkation card (ED Card). To enter Aruba you also must have a return ticket or onward ticket. You may not travel to Aruba with out already having a way out.
