There really is not enough information here to be able to answer your question. We need to know what happened and where you are in the immigration process.
Elliot Zarabi www.FreeCriminalConsultation.com 213-612-7720 This answer does not constitute full legal advise. I do not know the full details of the case and therefore cannot make a full determination on your case or your answer. I always recommend speaking to an attorney in detail regarding your case.
This is really an immigration consequences question because at this point you do not mention that you were arrested or that charges are pending. Therefore, I would search under immigration attorney on this website under Torrance, CA. If you get charged, then you should consult with a criminal defense attorney to determine how to plan your defense, and what the effect of a conviction would be. good luck.
This is an immigration issue, so I will add immigration to the suggested areas of law. If you need a criminal attorney later on then I would suggest reposting in the criminal area.
The response above is not intended as legal advice since it’s impracticable to provide thorough, accurate advice based upon the query without additional details. It is highly recommended that one should seek advice from a criminal defense attorney licensed in your jurisdiction by setting up a confidential meeting. Moreover, this response does not constitute the creation of an attorney-client relationship since this message is not a confidential communication because it was posted on a public website, thereby publicly disclosing the information, which is another reason to setup a confidential meeting with an attorney.
Move out ASAP. Your roommate sounds like a total maniac and his girlfriend may well be a dangerous corrupt cop. Stop communicating with this madman. Stop talking about this maniac to anyone. Do not talk to law enforcement ever about anything. If you are ever arrested do not utter as much as a syllable, immigration will try to find out who you are and whether you should be detained for possible deportation. And (you should do this first): get a local criminal attorney, you are being set up by a madman and his rogue cop girlfriend for prosecution and or deportation. Good luck.
