Check with Sheriff!
WARRANT:
First of all, you are looking in all the wrong places to find out if you have an outstanding warrant, especially a court house; a warrant search can be done very simply by either calling your County's Sheriff Offices or by visiting their website. For example
http://www.clackamas.us/safetyapp/warrants/
If by phone, ask the kind sheriff deputy who answers the phone for a warrant search on such-&-such person and you will be given an answer in less than 30 seconds. And no; you will not need give personal information like name and address because you will not be asked for them since warrants are public records and as such anybody can look them up. If you don't feel like socializing, then just visit the Sheriff's website where you will be asked for the first name, last name, and (depending on the county) a birth year and not the exact birth date, and once you press the submit button, it will take about 3 seconds for you to have the answer.
BUT BE AWARE of some private companies masquerading as official government websites proclaiming to provide all manner of records for free. One of those companies goes by DMV.org which will then hand you over to FreeBackgroundCheck.org
My take on the subject however is that you are wasting time and energy worrying about nothing; the situation you described will not cause the issuance of an arrest warrant, especially since the alleged victim has retracted the complaint. It is true however that when it comes to domestic violence, the matter will no longer be under the control of the victim once a repost is made to law enforcement who can make an arrest even when victim recants. But in order to prosecute, they will need the victim's testimony in court and if no such thing is forthcoming, then why bother with an arrest warrant.
But do look up for any warrants just to be on the safe side.
Last but not least, your status as an L.P.R. (Lawful Permanent Resident), otherwise known as a Green Card Holder, will not be in any danger as far as I.C.E. (Immigration and Customs Enforcement) is concerned. In case you have not heard, I.C.E. is the new I.N.S. whose sole purpose is to detain and remove those non U.S. Citizens who have accumulated indiscretions which amount to an Aggravated Felony for Immigration Purposes. While I do not wish to get into the very, very long winded and seemingly endless and on-going discussion of what constitutes Aggravated Felony for the Immigration Purposes, suffice it to say that your tiff with your ex does not qualify you for the honour of being arrested and deported by I.C.E.
Not that they wouldn't salivate at the mouth at the prospect, which they would. However, any detention and removal of an L.P.R. will have to result from a final ruling and conviction handed down by a criminal court judge. So, even assuming that there is a bench warrant out there for you, it will have no effect on your Green Card renewal as a warrant is NOT considered a FINAL conviction and RULING and as such not actionable.
