good sources of information, according to U.S. gov't

In January 2008, the Office of Chief Counsel submitted these documents, so that an asylum applicant from Togo would lose:
1. inf9rmation from the Immigration and Refugee Board of Canada: "country of origin research" "response to information request about the UFC party"
2. the application for a tourist visa, submitted years ago in Togo: it contained questions and answers. Does applicant remember the questions, and what answers were given when she asked for a tourist visa? Are her answers today, years later, the same?
3. information from "IRIN" which is a newspaper of the United Nations: www.irinnews.org
4. a cable from the US Embassy in Togo: a] students seeking F-1 visa often present fake documents from banks, and present fake high school diplomas. Sometimes the banks in Togo give information to the US Embassy upon request. b] many marriage certificates are fake: the filing number of the certificate does not exist; or it pertains to a different certificate c] sometimes, a medical certificate is issued by a clinic which does not exist! Sometimes, banks and Togo government offices cooperate and give information; sometimes they do not.
