After my arrest, charges were dropped. Then I received a letter from arresting agency stating your arrest deemed not arrest but detention only as per CA PC 851.6. I was finger printed.

There is a Department of Homeland Security USCIC (formerly INS) form fDS-156 where I have to answer to the question "were you arrested"- not sure if should write yes or no?

I am not a US citizen and my arrest record is haunting me with visa renewal pending. I have lost my sleep over this question on this form. If I answer NO and if INS does not give a damn to this PC851.6, I am screwed. If I answer Yes they will check with FBI and delay my visa anwyas. I have lost my sleep. Please help me.

Thanks a bunch.
