The self-employment visa application process entails obtaining some documents from Italy (police clearance, declarations/attestations from the relevant authorities, contracts with clients in Italy, etc.) before applying for the visa at the Italian Consulate/Embassy in the country of residence. Should you want to try, I advise that you contact the Italian Consulate/Embassy that has jurisdiction over your place of residency to check if they would issue a self employment visa to you (for your profession) and the list of documents they require. Please keep in mind that this type of self-employment visa is very difficult to obtain because of the uncertainty on which authority in Italy should be contacted for the issuance of the relevant attestations/declarations and for the requirements that may be set by the Consulate/Embassy.
