Via AKI:
A basic Italian language test that immigrants must pass to obtain a longterm residency permit entered into force on Thursday, the interior ministry announced. Foreigners can register online and will be summoned to sit the exam within 60 days of applying, the ministry said.
The exam tests comprehension of the most frequently used phrases and vocabulary needed to function and immigrants must score at least 80 percent to pass.
All immigrants who have been living legally in Italy for at least five years and want a long-term residency permit are obliged to take the test.
