Dev builds RAG system over USCIS appeal decisions for immigration prep

A developer created PetitionIQ, a platform using a RAG pipeline over 107 USCIS Administrative Appeals Office decisions to analyze visa petitions. The corpus is biased toward denials, so the system avoids approval probabilities and instead provides strength indicators with citations. The project aims to make case preparation more affordable than traditional attorney fees of $5,000-$15,000.
