A Nepalese refugee who fled his homeland to escape Maoist oppression has another chance to remain in the United States after a federal appeals court said an immigration judge held him to an “incorrect and overly stringent” standard in assessing his bid for asylum.

In a unanimous opinion issued Tuesday, the U.S. Court of Appeals for the Second Circuit said the immigration judge undermined the petitioner’s “mixed motive asylum claim” by forcing him to prove that political opinion was “the central reason” rather than “at least one central reason” for his persecution.
