Hi,
I was arrested for PC 243(E)(1) in 2004 in California.I was having an heated argument with my live-in girlfriend and when the police arrived, they arrested me for battery against her, and arrested her for PC 273.5 inflicting bodily injuries against me. The County DA subsequently notified us that no charges will be filed against either of us.
My I-140 petition for immigration has recently been approved, and I had answered in my I-485 application earlier 'NO' to the question of whether I had been arrested, convicted, etc for any offense without really thinking about it.
Would it be advisable (or possible) for me to submit an amendment to my I-485 saying 'YES' to the I-485 question with the DA's letter as clarification? Or should I seek an expungement of my arrest record instead?
I'm really worried if an arrest without charges filed be considered a DV record and hence affect my green card application?
I would be very grateful if I can receive advice on this. Thank you.
