Except in the case of a foreign corporation having personal service contract income to which section 543(a)(7) applies, a foreign corporation is not a personal holding company if all of its stock outstanding during the last half of the taxable year is owned by nonresident alien individuals, whether directly or indirectly through foreign estates, foreign trusts, foreign partnerships, or other foreign corporations.

See section 1504 and the regulations thereunder.
