22 CFR § 213.30 - Standards for suspension.
(a) The CFO may suspend collection action on a debt when:
(1) The debtor cannot be located;
(2) The debtor's financial condition is expected to improve; or
(b) Based on the current financial condition of the debtor, the CFO may suspend collection activity on a debt when the debtor's future prospects justify retention of the claim for periodic review, and:
(1) The applicable statute of limitations has not expired; or
(2) Future collection can be effected by offset, notwithstanding the 10-year statute of limitations for administrative offsets; or
(c) The CFO will suspend collection activity during the time required for waiver consideration or administrative review prior to agency collection of a debt if the statute under which the request is sought prohibits USAID from collecting the debt during that time. The CFO will ordinarily suspend collection action during the pendency of his consideration of a waiver request or administrative review where statute and regulation preclude refund of amounts collected by the Agency should the debtor prevail.
(d) The CFO may suspend collection activities on debts of $100,000 or less during the pendency of a permissive waiver or administrative review when there is no statutory requirement where he determines that:
(2) The Government's interest is protected, if suspension is granted, by the reasonable assurance that the debt can be recovered if the debtor does not prevail; or
(3) Collection of the debt will cause undue hardship to the debtor.
