A notice was posted today on the U.S. Department of State Website concerning necessary steps to take for children adopted from Vietnam to retain their citizenship.
From the notice;
The 2008 citizenship law of Vietnam requires that children adopted from Vietnam before July 1, 2009 must register with overseas Vietnamese diplomatic missions prior to July 1, 2014 to retain their Vietnamese citizenship (Art. 13.2 citizenship law of Vietnam).
Parents who wish their children (who were adopted prior to July 1 2009) to retain the Vietnamese citizenship should complete the process by July 1, 2014. Children adopted after July 1, 2009 automatically retain their citizenship.
For specific information about how to complete the registration process, please go to the Socialist Republic of Vietnam Embassy website.
