1) My case is Moral Turpitude. Do I have any hope left here for me?
- Yes. Petty offence Exception will still apply.
2) Do I need attorney to represent me during interview?
- Not really. Use your comfort level and the expense involved to decide
3) My arrest is recent (month old) and I filed I 485 year back. Do I need to inform INS voluntarily or I should wait for them to call me for interview and then tell them?
- Wait.
You won't have to tell them. They will know from FP if FP is done after the arrest. Otherwise, there wont even be an interview call. You will then have to deal wih this only if you apply for citizenship.
4) INS generally gives decision on application interview day or they just collect papers and information and send back to center?
- Decision. Even if the I-485 cannot be approved on the same day sometimes for reasons like name / IBIS check pending, you will be told that that is the only thing holding it up. You would not need to attend an interview again, and would know that you will be approved. If everything is OK, you will get your passport stamped during the interview.
5) In case they reject what Option do I left? Where and how I can appeal?
- I am not sure. You may need to ask a lawyer.
6) Does a decision to reject also affect my existing H1B status any way?
- I THINK not. It means you are inadmissible as a resident alien. Whether an offence is a deportable offence is a different question. Unlikely, with your case disposition, that it would affect your H1B status.
7) My application filed by company attorney. ...
- I don't know enough to prdeict where your case will be transferred. Intreview will happen where it is transferred.
- Take your own attorney. An attorney local to the center is better.
- Attorneys will charge for it. Ideally they should charge only for a couple of hours: $250 - $400. However, I have heard that many attorneys take advantage of the situation and charge up to $1,000. Mine charged very little.
If you need to send a private message, use that facility on this board. I am not certain I can help you if you give me more details. That is a job for a lawyer
Good luck!
