Deep Dive

How It Works

SpaceFill by SpaceLizit is an enterprise regulatory AcroForm automation engine engineered for corporate immigration practices, general counsel, enterprise mobility, and legal teams. By directly parsing the internal PDF AcroForm object tree rather than relying on brittle visual overlays, SpaceFill automates high-volume filings such as Form I-129 (927 fields), Form I-140, Form I-485, and Form I-765 in under 30 seconds. Traditional legal practices spend countless non-billable hours manually re-typing candidate resumes, biographical notes, tax IDs, and payroll schedules into repetitive federal documents. A single misplaced digit or shifted date can trigger immediate USCIS reject notices or costly Requests for Evidence (RFEs). SpaceFill ingests multi-source candidate documents—including digital resumes, Word .docx, and CSV records—and deterministically maps entities into their corresponding vector fields with sub-pixel comb calibration. Built on a zero cloud data retention architecture, SpaceFill processes client PII and payroll records locally within your browser perimeter. Documents are compiled directly into the native AcroForm tree, ensuring that official agency barcodes, government seals, and vector typography remain 100% crisp and audit-ready upon export.

Why High-Growth Firms Choose This

  • Slashes petition preparation turnaround from 45 minutes to under 30 seconds per beneficiary
  • Eliminates filing rejections and clerical RFEs caused by misplaced comb digits or formatting slips
  • Satisfies enterprise corporate risk committees with zero cloud storage of sensitive PII
  • Instant access to 20+ pre-calibrated official filings with no need to upload blank PDFs

Technology Under the Hood

SpaceFill parses the internal PDF dictionary hierarchy (AcroForm tree) to extract normalized coordinate bounding boxes, comb-digit matrix intervals, radio button hierarchies, and validation schemas. When source resumes or employer notes are attached, our localized entity extraction engine matches identities, employment histories, and federal identifiers without generative hallucination, injecting the resolved values directly into the PDF object stream.

Enterprise Security

  • Zero Cloud Data Retention (Local Browser Perimeter Processing)
  • Strict Non-Training Covenant (No Model Training on Client PII)
  • SOC 2 Type II Audited Infrastructure
  • AES-256 In-Transit Data Protection
  • Native AcroForm Object Tree Compilation (No Visual Scraping)

Time Savings

Slashes petition preparation turnaround from 45+ minutes to under 30 seconds per beneficiary.

Frequently Asked Questions

Q
How does SpaceFill populate complex PDF forms with 100% vector accuracy?

SpaceFill parses the internal AcroForm tree of your PDF to map every field's exact location, field type (text inputs, comb digits, checkboxes, dropdowns), and bounding coordinates. When you attach a resume or biographical notes, our mapping engine identifies matching data entities and populates all relevant fields directly into the PDF data objects—preserving original vector typography, agency barcodes, and official seals.

Q
What source document formats are supported by SpaceFill?

SpaceFill supports digital resumes and candidate profiles in PDF, Microsoft Word (.docx), CSV spreadsheets, and clean plain text (.txt). To ensure maximum extraction accuracy, documents should contain digital text layers rather than camera snapshots or flattened scans.

Q
How does SpaceFill protect client PII and data privacy?

SpaceFill is engineered with an absolute zero cloud data retention policy. Candidate resumes, payroll details, and identity documents are parsed locally within your browser perimeter. SpaceFill never stores or trains AI models on your confidential client information.

Q
Does SpaceFill handle comb boxes (digit-per-box) and checkboxes?

Yes. SpaceFill features specialized sub-pixel calibration algorithms tailored for official government comb fields (such as USCIS Alien Registration Numbers, SSNs, and EINs) ensuring every digit snaps cleanly into its designated boundary box.

Q
Can attorneys and paralegals review and edit fields before downloading?

Yes. SpaceFill provides an interactive side-by-side inspection studio where you can review every mapped field, adjust values in real time, and download the finalized, audit-ready vector PDF.

Q
Which official forms are already pre-loaded into SpaceFill?

Over 20 official federal filings are pre-loaded with pre-calibrated vector fields, including Form I-129 (H-1B, L-1, O-1, TN), Form I-140, Form I-485, Form I-765, Form I-9, Form I-130, Form I-864, Form N-400, ETA Form 9089, Form DS-160, and IRS Form W-4 / W-9.
