Prepare a stronger EB-1A, NIW, or O-1A petition before USCIS finds the weak spots.
CaseBuilder reads your documents, maps your evidence, builds the complete petition package, and runs an officer-style review to surface RFE risks — before you file, not after.

Most petitions don't fail because applicants aren't qualified. They fail because the record has gaps USCIS knows how to find.
EB-1A approval rates dropped to 67% in 2025. NIW dropped to 55%. RFE rates reached 40-50%. The most common reason: weak corroboration, vague impact claims, and missing support that could have been caught before filing.
What the officer-style review looks like
CaseBuilder flags weak spots the way an adjudicating officer would — before you file.
