An immigration hearing has taken place for U.S. President Barack Obama's Kenyan aunt, who is seeking asylum in the United States.

Zeituni Onyango testified for two and-a-half hours Thursday at an immigration court in Boston, Massachusetts, asking that she be allowed to remain in the country.

Two doctors also testified in support of her case, which includes an appeal for asylum based on medical reasons.

No immediate decision was made in the case.  Lawyers say a follow-up hearing has been scheduled for May 25, but say there may be a decision before then.

Onyango moved to the United States in 2000.  A judge rejected her first request for political asylum and ordered her deportation in 2004.  But Onyango never left.

Her immigration status became widely publicized just days before the 2008 presidential election.

Mr. Obama has said he did not know his aunt was living in the country illegally and that all appropriate laws should be followed.  

Both the White House and Onyango's lawyer (Margaret Wong) say the president has not been involved in the case.

Onyango is the half-sister of Mr. Obama's late father.  The president referred to her as "Aunti Zeituni" in his memoir.
