KANSAS CITY, Kan. (AP) — A federal appellate court will hear the case of a retired Army lieutenant and his wife who are seeking to keep their adopted Korean-born daughter in the country after she graduates from college.

Attorneys for the family of Hyebin Schreiber said Monday that the hearing is set for next month. Schreiber was 15 when she went to live with her aunt and uncle, Army veteran Patrick Schreiber, in Lansing, Kansas, because of family problems in Korea.

Schreiber’s deployment to Afghanistan caused the couple to put off her adoption until she was 17. The age limit for a foreign-born adopted child to become a naturalized U.S. citizen is 16.

She currently is in the U.S. legally on a student visa, but could be forced to leave after she graduates from the University of Kansas.
