I know what you are saying. It was true atleast till sometime back. However, I gather from other messages on the forum, that premium processing seems to be converging with the normal processing now-a-days, meaning you can expect RFEs, NITDs...
To me, it seems like they are cracking down all out of status cases and are particularly harsh on "bench" cases because they have a potential for security loop hole? Also, I'm afraid they are questioning hiring people without a formal CS/CE degree for a CS/CE job. Their process sure did change in the last few months. I guess, this is one way to control the number of non-immigrants without changing laws. Personally, I don't have a problem with that if they don't delay processing cases for months at a stretch and give a leeway for a couple of months, if one loses his/her job. After all, I'm sure, most of us don't want to be in this country illegally, right.
