Winfred has been living in Bulgaria since 1980 and has never left the country. He graduated from the Technical University of Sofia and was planning to return to Tanzania, where he would start working for a company that sent him to study in Bulgaria. However, due to the complex political situation in his country, he lost his Tanzanian citizenship. There is no country to which he can be returned. Like many other stateless people, he has been detained for removal and then released back in Bulgaria on five separate occasions since 1998. Winfred's dream is to pass on his knowledge and to open a school where he could teach mathematics. Winfred is an example of how Bulgaria wastes human potential by not providing documents and the right to a legal residence to hundreds of people.
