owned and held by a nonresident not a citizen of the United States shall be deemed property within the United States. With respect to estates of decedents dying after December 31, 1969, deposits with a domestic branch of a foreign corporation, if such branch is engaged in the commercial banking business, shall, for purposes of this subchapter, be deemed property within the United States. This subsection shall not apply to a debt obligation to which section 2105 (b) applies or to a debt obligation of a domestic corporation if any interest on such obligation, were such interest received by the decedent at the time of his death, would be treated by reason of section 861 (a)(1)(A) as income from sources without the United States.
Notwithstanding the preceding sentence, if any portion of the interest on an obligation referred to in paragraph (3) would not be eligible for the exemption referred to in paragraph (3) by reason of section 871 (h)(4) if the interest were received by the decedent at the time of his death, then an appropriate portion (as determined in a manner prescribed by the Secretary) of the value (as determined for purposes of this chapter) of such debt obligation shall be deemed property within the United States.
then that proportion of the fair market value of the stock of such foreign corporation owned (within the meaning of section 958 (a)) by such decedent at the time of his death, which the fair market value of any assets owned by such foreign corporation and situated in the United States, at the time of his death, bears to the total fair market value of all assets owned by such foreign corporation at the time of his death, shall be included in the gross estate of such decedent. For purposes of the preceding sentence, a decedent shall be treated as owning stock of a foreign corporation at the time of his death if, at the time of a transfer, by trust or otherwise, within the meaning of sections 2035 to 2038, inclusive, he owned such stock.
the President shall proclaim that the tax on the transfer of the estate of every decedent who was a resident of such foreign country at the time of his death shall, in the case of decedents dying after the date of such proclamation, be determined under this subchapter without regard to amendments made to sections 2101 (relating to tax imposed), 2102 (relating to credits against tax), 2106 (relating to taxable estate), and 6018 (relating to estate tax returns) on or after November 13, 1966.
