OK what I’ve found so far is at http://www.state.gov/documents/organization/109065.PDF
Page 1 says parents or legal guardians cannot renounce or relinquish the nationality of their children or wards. References 7 FAM 1290 for guidance on loss of nationality and minors. (I will post this one separately).
Page 3 in section g says the expatriating act needs to be done overseas.
Page 5 in section (4) it says for guidance on documentation required for loss of nationality cases prior to 1984, consult the Ask-CS-L-Dom-Post@state.gov.
On pages 6 and 7 it talks about who approves the CLN.
Section b (1) at the top of page 6 says its the division chief in the office of American citizen services and Crisis Management (CA/OCS/ACS )
And in (3) (c) it says they have to go to yet another department in cases involving minors.
Section a on Page 7 says secretary of state has authority to determine whether a person not in the u.s. is a u.s.citizen
OK here’s the FAM 1290 link:
http://www.state.gov/documents/organization/120538.pdf
CA/OCS/L is the Consular Affairs office of Overseas Citizens Services office of Legal affairs.
(Not sure what L/CA is )
Here’s the section about minors: note page 2 section i (1), (2).
Section 2 says “children under 16 are presumed not to have the requisite maturity and knowing intent” in regards to renouncing citizenship.
I will post the full text in the next post.
