Zars Monkey

i got here legally, I am out of status, ok in order for my step dad to submit the i130, he needs to show that his last marriage was legally terminated. L A county says that a lot of those docuemnts from back in those days they are not in the "chip" they straight up told me that chances are that I am not gonna find it.. so if INS is asking for a document that i cant locate which is the divorce decree, what are my options, I am sorrry I made it so hard for you to understand, I been having a hard two years lol!! my daddy is been really sick

So I been in the US for about 9 years, my stepdad is been a permanent resident for 30, married to my mom for 20, we have a pretty good record, I was well known in school cuz I was very active in the clubs, why cant I apply for a gc? my dad divorced his exwife in 1985 they both walked into the lawyers office sign all the documents, and finalize it right in there since it was a mutual agreement. they never saw each other again, This woman has not been able to give me any information, and i have a really strong feeling is because she doesnt care much. no returned calls, no emails, my step sister try to get the date and case number and nothing, so I been in touch with the LA recorders office and there is nothing honestly i dont even thing that there is a marriage showing up either and i t could be because my dad didnt have his green card then, I have poa on my dad, and Im also his SSB payee, I just finished all this process and the ex came up in his record but I just had the federal employee correct that on his ss.. now how do I help my dad to submit the 130s for us and do his CS, should i risk it and play dumb about that marriage? or should I write a really nice letter to USCIS along with the forms and explain the situation, perhaps I'll just dig my self in a bigger whole. If there is anyone out there with any sort of imformation that can help me finally start this process? all the layers wanna take the case, but the law is the law they just want money, when I talk to USCIS they dont help much eather... Thanks guys, i hope my email wasnt too long, I spent over an Hr and a half looking for a similar case but i couldnt find anything that is actually relatible to my case
