Besides senators, congressmen,etc, there is also Office of Inspector General, which audits DOL's work constantly. They already have a work plan for FY 2005, and that plan does not include our Philly/Dallas questions. However, it may make sense to make them aware of the problem.
As an example of their work you can review
http://www.oig.dol.gov/public/reports/oa/2004/06-04-004-03-321.pdf (Restoring Section 245(i) of the Immigration and Nationality Act Created a Flood of Poor Quality Foreign Labor Certification Applications Predominantly For Aliens Without Legal Work Status), discussing effects of 245(i) on LC with all the numbers and details. That document seems to suggest that many applications filed in the first 4 months of 2001 should produce NOF, which may explain why we don't see many approvals for those months.
