Social Security has an office whose job is responding to requests made under the Freedom Of Information Act (FOIA). They respond directly to those making the requests but from time to time they also post "Proactive Disclosures" online, apparently derived from items they're already disclosed in response to individual requests. They're just made a huge dump of 51 Proactive Disclosures. I'll pull out some items to post about here when I have time but you may want to take a look at the list now.
By the way, they have lists of Top 100 Firms & Reps by Fee and Top 300 Fee Payments These lists are inaccurate. I know because my name and my firm's name are on the lists. I know the figures given for me and my firm are way off. I have no idea how they could be so far off. I also caution that those who have never tried to practice Social Security law have no clue about the expenses involved or the sort of investment required. The profit margin, when there is one, is a much smaller percentage than you would think. If you think that practicing Social Security law is a fast track to riches, I invite you to give it a try but know that there will be months, especially in the first few years or if there's a pandemic, when you have to sweat covering your overhead. There are reasons almost no one is leaving the employment of the Social Security Administration to hang out a shingle and represent claimants.
