Understanding VisaDocAssist Technical Audit Results
VisaDocAssist evaluates uploaded photographs and supporting PDF files against published electronic consular gateway rules. Results are categorized using deterministic thresholds.
The file strictly conforms to all published technical parameters for the target portal: resolution, aspect ratio, byte ceiling, background contrast, and valid binary magic bytes.
The file breaches an automated portal gateway rule (e.g. over 240 KB for CEAC, over 4 MB for IRCC, password-protected PDF, or eyeglasses present). Submitting will trigger an upload error.
Flags consular post variations (such as Schengen national upload differences) or items that depend on consular officer discretion rather than automated machine scanning.
Safe Client-Side Auto-Fix Mechanics
When auto-fixing a file, VisaDocAssist performs mathematical transformations only:
- Geometric Crop: Aligns framing to required 1:1 or 35x45mm ratios without warping facial features.
- Binary-Search Compression: Re-encodes JPEG quality until file size falls under the official KB threshold without dropping below required pixel minimums.
- Zero AI Alteration: Never generates artificial faces, alters facial landmarks, or smooths skin.
100% Browser-Side Privacy Architecture
Your identity documents, photographs, and financial records remain strictly private:
- No Network Transmission: Processing executes entirely in your browser using HTML5 Canvas, Web APIs, and client-side WebAssembly.
- No Cloud Storage: VisaDocAssist operates without databases or document storage buckets.
- Instant Destruction: All in-memory buffers are cleared when you close or refresh the page.

What VisaDocAssist Checks vs. What We Cannot Determine
To maintain absolute editorial and technical integrity, VisaDocAssist clearly defines the boundaries of our client-side software.
Our software runs local deterministic evaluations against published consular upload gates:
- Exact pixel dimensions and millimeter ratio matching
- File size ceiling enforcement (e.g., under 240 KB, 2 MB, 4 MB, 5 MB)
- Binary file signature inspection (detecting spoofed extensions or damaged headers)
- PDF page count, rotation angle, and encryption/password detection
- Image background luminance and contrast threshold evaluation
- Signature aspect ratio, stroke density, and background purity evaluation
- Compliant government file naming standard application
VisaDocAssist is an independent preparation and checking tool. It is not a government website and does not guarantee visa approval or document acceptance:
- Cannot evaluate visa eligibility, financial adequacy, or applicant qualifications
- Cannot predict consular officer discretionary decisions or interview outcomes
- Cannot verify whether uploaded identity documents are legally authentic or forged
- Does not constitute legal or immigration representation or legal advice
- Has zero affiliation with or endorsement from any government agency or embassy
Requirements can change without notice. Individual consular posts may enforce local photo dimension interpretations or supplemental proof of funds. Always verify current requirements on the official government website before submitting your final dossier.
Technical requirements for this category are extracted directly from official published instructions by U.S. Department of State - Bureau of Consular Affairs for jurisdiction USA.
