State immigration law determines whether a person is an alien, and the associated legal rights, duties, and obligations of aliens in Italy. It also provides means by which certain aliens can become naturalized citizens with full rights of citizenship. The role of Legal Advisor of our law firm in Italy (Milan, Bologna, Rome) in a typical transaction is as follows.
Immigration law serves as a gatekeeper for the nation's borders: it determines who may enter, how long they may stay, and when they must leave. An "alien" is any person who is not a citizen or a national of Italy. There are different categories of aliens: resident and non-resident, immigrant and non-immigrant, documented and undocumented ("illegal").
The Republic of Italy, like many countries, has limited immigration, and there is a variety of visas, permit cards, and work permits, which require legal advising in favor of business and non-business aliens in order to start sojourner life, activity, or enterprise. In effect, the goals in immigration policies, which are implicated by visas and cards, are achieved when granting or denying visas. Thus, where there is an official practice, aliens need the aforementioned legal advising. There are two types of visas: immigrant and non- immigrant. Non-immigrant visas are primarily issued to tourists and temporary business visitors. Non- immigrant visas are divided into many more categories, and the number of visas in most categories is not limited.
Only a few categories of non-immigrant visas allow their holders to work in Italy. Immigrant visas permit their holders to stay in Italy permanently and ultimately to apply for citizenship. An alien who has an immigrant visa is permitted to work in Italy. Many immigrant visas are also subject to per-country caps.
Sometimes, the Italian Republic recognizes to non-immigrant aliens, by means of country reciprocity, the right to start a business and purchase goods in Italy. It is appropriate to timely ask a lawyer when this exceptional country reciprocity does work.
