Italy student visa cover letter

I need a Visa cover letter for italy student visa for bachelors in business and economics.
What are all the things to include?
Can anyone provide me with a sample?

Visa cover letter requirements vary from country to country. The specifics are part of the student visa application packets. The standard information though, pertains to the student's ability to study abroad without having to work and, proof of ties to your home country. The idea, is to convince the visa officer that all you will do is study, with a strong desire to return home after completing the degree. Ties to home are best proven through your parent's ability to support your overseas education and work opportunities at home. A familiaritywith the rules governing your stay as a student will also help.
