I am studying in Italy now. Can I travel to Ireland?

Ireland is not a Schengen country. You need a visa to love, including Britain. You need about nine things, such as hotel reservation, air ticket, passport, visa for more than half a year, photos and so on. And then you can come down in about 2 weeks, usually 2-6 months. But if you have a visa from a Schengen country, you don't have to go to other Schengen countries. For example, if you apply for Holland, you can go to France.
