Attorneys and aid workers say there are a variety of reasons some people may not come forward to make a claim.
Some lack tax returns and other documentation they need. Others are overwhelmed by the paperwork.
Some don't want to admit they can't read. And some worry that their failure to pay taxes on past cash income might get them in legal trouble.
Charitable groups are trying to find and help such people. One group, Horizon Relief, is contacting seafood-related businesses along the coast, seeking information on employees who might need help.
