Per U.S. Circ. 38a, the following countries are not participants in the Berne Convention or Universal Copyright Convention and there is no presidential proclamation restoring U.S. copyright protection to works of these countries on the basis of reciprocal treatment of the works of U.S. nationals or domiciliaries:
Eritrea, Ethiopia, Iran, Iraq, Marshall Islands, Palau, Somalia, Somaliland, and South Sudan.
As such, works published by citizens of these countries in these countries are usually not subject to copyright protection outside of these countries. Hence, such works may be in the public domain in most other countries worldwide.
However:
Works published in these countries by citizens or permanent residents of other countries that are signatories to the Berne Convention or any other treaty on copyright will still be protected in their home country and internationally as well as locally by local copyright law (if it exists).
Similarly, works published outside of these countries within 30 days of publication within these countries will also usually be subject to protection in the foreign country of publication. When works are subject to copyright outside of these countries, the term of such copyright protection may exceed the term of copyright inside them.
Unpublished works from these countries may be fully copyrighted.
A work from one of these countries may become copyrighted in the United States under the URAA if the work's home country enters a copyright treaty or agreement with the United States and the work is still under copyright in its home country.
Note that it may still be copyrighted in jurisdictions that do not apply the rule of the shorter term for US works (depending on the date of the author's death), such as Canada (70 years p.m.a.), Mainland China (50 years p.m.a., not Hong Kong or Macao), Germany (70 years p.m.a.), Mexico (100 years p.m.a.), Switzerland (70 years p.m.a.), and other countries with individual treaties.
