I guess they are "working really hard" (ha-ha) to organize that backlog reduction center (see
http://www.murthy.com/news/n_ombrev.html).
Seriously though, it just another proof of the rule: when there are no mechanisms of public control or the public lacks interest to the beuracratic machine it gets out of hand and does whatever it wants.
I am from Russia and observed the beuracracy's inefficiency up close over there for many years.
Human nature is the same anywhere in the world: if you can get away with not doing your job and still get paid you probably will not do your job. So they do and always will, until there is some stimulus, either positive (rewards for more applications processed), or negative (punishments for not meeting deadlines or performance tolerances), or both.
Plus, in general it's very covenient for this country to have such workers bound to their employers like slaves or serfs who pay taxes and social security but don't have rights for any benefits, whose wives are not allowed to work for all these years or even get a driver's license, who can be kicked out any moment if they get laid off and so on.
They'd rather give green cards to illegal Mexicans than to us! See Kerry's last speeches and democrat's "comprehensive immigration reform" SOLVE act. It suggests to give a gc to any ILLEGAL who has been here for more than 5 years and paid taxes for more than 2 years, but it doesn't even mention LEGALS, us, stuck in the DOL/USCIS process, legally working here sometimes much longer than that and who has paid much more in taxes than those poor illegal wetbacks!
