(a) DESIGNATING CENTER OF MAIN INTERESTS. A petition for recognition of a foreign proceeding under chapter 15 of the Code shall state the country where the debtor has its center of main interests. The petition shall also identify each country in which a foreign proceeding by, regarding, or against the debtor is pending.
(b) CHALLENGING DESIGNATION. The United States trustee or a party in interest may file a motion for a determination that the debtor's center of main interests is other than as stated in the petition for recognition commencing the chapter 15 case. Unless the court orders otherwise, the motion shall be filed no later than seven days before the date set for the hearing on the petition. The motion shall be transmitted to the United States trustee and served on the debtor, all persons or bodies authorized to administer foreign proceedings of the debtor, all entities against whom provisional relief is being sought under § 1519 of the Code, all parties to litigation pending in the United States in which the debtor was a party as of the time the petition was filed, and such other entities as the court may direct.
