From your question it sounds like you have been charged with Assault IV - Domestic Violence. If the alleged incident happened in the City of Redmond, the case will be prosecuted by the City of Redmond Prosecutor's Office. There are two main prosecutors for the City of Redmond. I have found them to be fair and would likely be interested in hearing about her claims of making a false report. Still, many prosectors expect the alleged victims to change their stories over time. It is important to get an experienced domestic violence attorney on your side as soon as possible. The good news is that there are many options in a City of Redmond matter that can lead to your case being dismissed. As a non-citizen, it is extremely important that any disposition you enter is "immigration safe." I agree with the other answers here, you need to find an attorney as soon as possible.

Concur. Writing to add that if you cannot afford to hire private counsel then you should apply for a public defender. A DV conviction will have serious life-long ramifications, and if your wife recants you will have an even worse problem on your hands.
