Certificate of Loss of Nationality

The form is prescribed by the Secretary of State under the Immigration and Nationality Act of 1952.

However some provisions of U.S. regulations require a CLN be issued in order to recognize a person as a non-U.S. national even if as a matter of law that person is already probably not a U.S. national.

One example of this are FATCA provisions as currently adopted in the US Code of Federal Regulations.

Persons lacking an alternate nationality or refusing to declare one at the time of application may be listed as being stateless on their CLN.

Unlike other countries, the United States allows persons to renounce their citizenship even when that person would become stateless upon loss of United States nationality.
