The bringing of charges serves to extend you past your ETS. If you have a court date, you obviously have counsel, so they should explain this to you in more detail as it relates to your case. If you haven not already done so, you can also retain civilian counsel.
Assuming you are still within the time frame to file an appeal of that decision, you should retain an attorney to review the entire transcript and give you their assessment of the likelihood of success on appeal. While I am not a WA lawyer, I do a lot of appeals and this is how I review cases. I am sure you can find the same arrangement with a WA lawyer.
Every day I am astounded at how people show up in court. I tell all my clients to wear a shirt and tie. Don't look like you are going to the prom, but don't dress like you are hanging out with your friends. No matter whether it makes a difference or no, show respect to the court.
Your question is very hard to understand, but it is possible the attorney knew there was no reason to do the preliminary hearing because of your boyfriend's immigration status. In other words, nothing he could say would have mattered. But I am only guessing. Your boyfriend needs to have a long hard talk with his lawyer and find out what is going on. If he is not comfortable he should consider hiring a different one.
it is impossible to answer the question based on this limited amount of info. But your lawyer will likely file a motion to suppress, which is when it will all be sorted out. Even if every lawyer here tells you the search was illegal, we don't get a vote. Only the judge does.
No. He has to wait six months, and must apply within 15 years, but there are no "automatic" upgrades, and statistically few are upgraded. But every case stands on its own, and he would be wise to have an attorney review his case. Make sure he keeps all the paperwork he received when discharged.
I have done a number of these cases in which a police cadet lies and says she is 18 but looks much younger. Best advice is never engage any such person in a conversation and for goodness sake never send or received nude pictures over the Internet. You are asking for trouble.
