CIS Ombudsman was specially created to look into issues related to immigration . . . so probability of getting a response from this office would be much higher.
I sent a petition to CISO requesting help with my case 3 weeks ago. I also followed up w/ a phone call. CISO said I should hear from DFLC in 45 days - well, according to the Backlog Public Disclosure System my case was certified today - (I will of course believe this only when I get the hard copy notification of LC!). Coincidence? Perhaps . . .
Contacting senators did not help at all!
Contacting your local congressman may be more helpful. For filers in NY living in Queens/Brooklyn, Anthony Weiner is the Congressman to contact.
