If you do not already have a valid passport, you should apply for one immediately as acquiring a new passport can take up to 8 weeks. If you already have a passport, check the expiration date to make sure that your passport will be valid at least 6 months beyond the date on which you plan to return to the U.S.

Study Visas for Italy
The visa application process can seem complicated at first, but provided you review the information on the Italian consulate’s website carefully and allow yourself adequate time to collect the required documents, you should not encounter any significant problems.
The biggest obstacle to acquiring a study visa is time. If you require a visa, it is very important that you make an appointment at the Italian consulate in your jurisdiction as soon as you are accepted into the study abroad program. The visa sections of consulates are very busy and might not have appointments available close to the time you request, so making an appointment as soon as possible is crucial to getting your visa in time.
The Italian visa process is administered by consulate general offices throughout the US. Each consulate office oversees the visa process for residents of a specific jurisdiction of states, and each consulate office has a slightly different application procedure.You must apply at the consulate which covers the state in which you are a resident or, with some consulates, the state in which you are a registered student.
