SpaceLizit auto-fills the I-129 H-1B supplement, generates the specialty occupation support letter, syncs LCA prevailing wage data, and flags RFE triggers — before USCIS sees the petition.
The H-1B petition consists of Form I-129 (Petition for Nonimmigrant Worker) with the H Classification Supplement, plus a specialty occupation support letter drafted by the employer. It is the most scrutinized employment-based nonimmigrant petition — USCIS issues RFEs on 20–30% of H-1B petitions, primarily for specialty occupation failures. SpaceLizit's AI reduces H-1B RFE rates to under 3%.

SpaceLizit catches all of these before you file.
USCIS officers challenge whether the job requires a bachelor's degree in a specific specialty field. Weak support letters that don't connect the job duties to specific degree requirements are the #1 H-1B RFE trigger.
The LCA prevailing wage must match or exceed the actual wage offered on the I-129. Any discrepancy — even $1 — triggers an RFE or denial.
The Standard Occupational Classification code on the LCA must align with the actual job duties described in the I-129. Mismatches trigger both USCIS and DOL scrutiny.
For IT consulting or third-party placement H-1Bs, USCIS requires a complete worksite itinerary. Missing or vague itineraries are a leading RFE trigger.
The beneficiary's degree field must directly relate to the specialty occupation. Attorneys must explicitly argue the nexus — USCIS does not assume it.
Three steps from LCA to filing-ready petition package.
SpaceLizit pulls the certified LCA directly from the DOL FLAG system, auto-populates the I-129 and H Supplement with LCA wage data, worksite information, and SOC code — and flags any wage discrepancy before filing.
SpaceLizit generates a specialty occupation support letter tailored to the specific SOC code, degree field, and job duties — arguing the degree-to-job nexus and addressing the top RFE patterns for that occupation. Attorneys review and sign.
SpaceLizit runs the complete petition package through its pre-filing audit: checking specialty occupation argument strength, itinerary completeness (for consulting placements), wage compliance, and SOC code consistency — outputting a risk score and flagged items for attorney review.
SpaceLizit validates every item before generating your petition package.
