I think this matter has not been discussed. Many big companies laid off people during the hard times and it has affected labor and 1-140s for many people. Whoever passed this stage and applied for I-485 should have no problem, but I don't think so. I believe many petition approvals might have been delayed because of this fact also. CSC might delay your petition if you work for one those big companies with layoff history.
