A property and casualty insurer is organized under the laws of the Republic of Ireland and admitted to transact insurance in Pennsylvania. For PA purposes, this insurer is classified as:

Why this is the answer

Under 40 P.S. § 386, a 'domestic' insurer is organized under Pennsylvania law, a 'foreign' insurer under another U.S. state's law, and an 'alien' insurer under the laws of a country other than the United States. An Irish-chartered carrier is therefore alien for Pennsylvania purposes, even after it secures a PA certificate of authority. 'Reciprocal' describes corporate form (subscribers exchanging reciprocal or inter-insurance contracts under 40 P.S. § 961 et seq.), not domicile, so it does not apply.
