Del. Code tit. 8 § 518
All corporations incorporated and existing under the laws of this State, all of whose assets are located in any country from which it is impossible to remove such assets or withdraw income, or whose assets are located at any place where it is made unlawful by any law of the United States of America now or hereafter enacted or by any rule, regulation or proclamation or executive order issued under any such law, to send any communications, may, in the discretion of the Secretary of State, be relieved and freed from any and all assessment of franchise taxes provided for by this chapter and such corporations may further be relieved by the Secretary of State of the necessity of filing any state reports due or required.
The Secretary of State shall administer this section and may require such evidence, submitted by any officer or agent, as in the Secretary of State's judgment may be necessary or desirable to determine whether or not a corporation deserves such relief from taxes and the filing of reports, and may make such regulations in relation thereto as the Secretary of State may deem desirable or necessary.
