According to a USCIS Press Release: “U.S. Citizenship and Immigration Services (USCIS) announced today an extension of Temporary Protected Status (TPS) for nationals of Sudan through May 2, 2010. The extension will offer those who have already been granted TPS an opportunity to re-register and maintain their status for an additional 18 months. TPS does not apply to Sudanese nationals who entered the United States after Oct. 4, 2007.”
The USCIS has also released a Q&A on this subject.
