TOPEKA, Kan. (AP) — Some foreign teachers recruited to work in Topeka schools are facing the possibility having to return home because of problems with their applications for permanent residency. The Topeka school district currently has 29 teachers from abroad. In June, the district found out that some of the teachers' applications for permanent residency had been rejected. The district is appealing, but if the appeal is denied, six teachers will be sent home. The Topeka Capital-Journal reports the U.S. Department of Labor rejected the district's argument that there is a shortage of teachers qualified and willing to do the jobs the foreign teachers have filled. The district says it has a continuing problem filling some teaching jobs, particularly special education, math and science positions.
