You need to send in certain supporting documents along with your application form. If you don't, your application will be considered incomplete. Among these papers are the following:
Visa Application Form: You must have a visa application form that is filled out correctly and signed. The form can be
downloaded or picked up at a place where visas are given out.
Photographs: Two color photos taken in the last three months are needed. The picture must show your face and the tops of your shoulders. In the photo, you can't wear any hats or glasses.
Financial Documents: You will need to show that you have enough money to live on during your time in Aruba by bringing documents like your paystubs from the last three months and bank statements.
Plan of travel: It would be best to tell them what you want to do and where you want to go while in Aruba. You also need to show proof that you have a hotel reservation.
Vaccination Certificate: If you are from a country where Yellow Fever is a risk, you must show proof that you have been vaccinated against it.
