Fortunately, though the introduction of "intent" into the clauses can be worrying, presumption of innocence is still the base premise the dept uses:
ADMINISTRATIVE STANDARD OF EVIDENCE
As already noted, the actions listed above can cause loss of U.S. citizenship only if performed voluntarily and with the intention of relinquishing U.S. citizenship. The Department has a uniform administrative standard of evidence based on the premise that U.S. citizens intend to retain United States citizenship when they obtain naturalization in a foreign state, subscribe to routine declarations of allegiance to a foreign state, or accept non-policy level employment with a foreign government.
DISPOSITION OF CASES WHEN ADMINISTRATIVE PREMISE IS APPLICABLE
In light of the administrative premise discussed above, a person who:
(1) is naturalized in a foreign country;
(2) takes a routine oath of allegiance or
(3) accepts non-policy level employment with a foreign government
and in so doing wishes to retain U.S. citizenship need not submit prior to the commission of a potentially expatriating act a statement or evidence of his or her intent to retain U.S. citizenship since such an intent will be presumed.
When, as the result of an individual's inquiry or an individual's application for registration or a passport it comes to the attention of a U.S. consular officer that a U.S. citizen has performed an act made potentially expatriating by Sections 349(a)(1), 349(a)(2), 349(a)(3) or 349(a)(4), the consular officer will simply ask the applicant if there was intent to relinquish U.S. citizenship when performing the act. If the answer is no, the consular officer will certify that it was not the person's intent to relinquish U.S. citizenship and, consequently, find that the person has retained U.S. citizenship.
At first glance, I worried that more of
Ashcroft's wet dreams had crept into law.
Section 501, "Expatriation of Terrorists": This provision, the drafters say, would establish that an American citizen could be expatriated "if, with the intent to relinquish his nationality, he becomes a member of, or provides material support to, a group that the United Stated has designated as a 'terrorist organization'." But whereas a citizen formerly had to state his intent to relinquish his citizenship, the new law affirms that his intent can be "inferred from conduct." Thus, engaging in the lawful activities of a group designated as a "terrorist organization" by the Attorney General could be presumptive grounds for expatriation.
