Second Circuit: Kakar v. USCIS

 Agency's ruling was arbitrary and capricious in that it didn't explain how petitioner's conduct would have been illegal in the United States, given that there is a genuine and reasonable dispute as to the context of the events, and also as to the affirmative defense of duress.  

(Although petitioner had challenged for lack of substantial evidence, vacated and remanded to agency as arbitrary and capricious.)
