Where can I get information about the FAA "restricted like" license to fly a N aircraft in Italy / Europe? I have recently bought a N-REG C172 in Italy since 2008 and in fact I have been told by the Italian NAA that my EASA License will be valid limited for flights in Italy. I understand if I wish to fly in other EU countries I should apply for a FAA "Restricted like" License which I can obtain symply by giving a short english language check in recognized FAA offices in Italy. Any Idea about this "restricted" option? Whom should I ask to get more info?
I don't know what an FAA "restricted" license is, but I guess it may be a foreign-based license issued under 14 CFR 61.75; see this answer for more information.

It's an FAA private license that's linked to your Italian one and it gives you all the privileges of a regular FAA private license, including operating N-reg aircraft anywhere in the world. But note that if your Italian license has more restrictions than the FAA one (e.g. no night flying) then you still have to obey those restrictions.

The process to get one is described here but I believe you have to physically visit an FAA office in the USA to get it.
