labordrags, they won't do anything at DOL upon your request (unless you ask for a screenshot, which I also doubt). This has to be done either by your lawyer, or employer, if you don't have a lawyer. I had to contact DBEC myself and my employer agreed to do that for me. I should admit that they are incredibly slow and incompetent, so you should give them some time to respond. In my case, it took my employer 2 unanswered voice messages, 2 faxes and about 3 emails to get my issue addressed. It was done roughly within 2 weeks. So don't give up and ask appropriate people to help you, don't do it yourself.
As for congressmen & senators, I don't think they will be able to do much. First, they don't care about you (and us in general) since we are not constituents and cannot vote (and that's what matters for them). Second, I believe that all immigration authorities are mostly immune from direct influence from all the politicians. So don't waste your time.
I understand your frustration and hopefully we all get certified in this mess and move on to another step.
