Her case has been pending since 1997 -- so she has been in limbo for 4 years! Since then, she has had a daughter and is expecting another child this year. The fact that she has 2 U.S. citizen children will not prevent her from been sent back to Sierra Leone if the BIA reverses the Immigration Judge's grant of asylum (although the whole case can then be appealed to the Third Circuit and ultimately the Supreme Court).
But, you can just imagine how stressful this is for her to remain in limbo for so long! You can read about her story at, http://www.lhj.com/health/news/seeking-political-asylum-in-america/
