Legal Question in Criminal Law in California

Re: federal conviction using previous name

"Techinically the name on my conviction was not a US citizen and all my records had my new name." Names are not citizens, nor are they parties to legal disputes. Regardless of the name that appears in the records, you are the one who was convicted.

If giving the trial court this information would have helped you then you should have done so. You can't complain that the prosecutor didn't do this for you, and you don't really know why she didn't anyway.

What can happen to you? The same thing that can happen to anyone convicted of the same crimes. You haven't made it clear why you think something unusual might happen in your case.

If you are worried about immigration consequences you should post your question under that heading. My sense is that the government would have to revoke your citizenship before it could deport you, though I could be wrong on that point. I also don't know whether a criminal conviction like yours is grounds for such revocation, but an immigration specialist probably would.
