Dr. NIW, Dr. EB1A, Dr. EB1B, Dr. I-485, and Dr. EB-5 each guide you through the specific statutory criteria and requirements for that petition category.
Import documents by URL or email, run citation analysis, and let the assistant tell you exactly what supporting material is still missing.
Draft petition letters, sections, essays, and exhibits with section-by-section assistance — petitions, RFE responses, and admissions documents included.
AI fills the USCIS forms and an in-browser editor lets you highlight, cut pages, and annotate evidence PDFs, with full version history to revert any change.
