I have no idea why I got two LUDs. I just happened to log in my USCIS account and found the first LUD. Due to curiosity, I logged in again the second day and found second LUD. So far, nothing has happened to me yet, I mean for approval. No matter whatever reason it is, I think I need luck now for processing the case or for speeding up the process.
For your interest, I work on nanofabrication and nanofluidics.
I have a friend working on cancer research as well, I think it is also national interest since it belongs to life science. I hope we can get cases processed by the end of this year. Let's have fingers crossed and see how the process's going.
