I did just that. Reclaim the Records files lawsuits against a lot of US government entities to force them to release records to the public, which they then publish. They have an amazing record of accomplishment. I often see citations on familysearch attributing a record to Reclaim the Records. You don't have to have had dealings with USCIS to be able to benefit from them releasing records that may later be of use to you when they are available publicly.
This is about trying to keep costs as low as possible to get records - it's in the interests of everyone who works on genealogy.
