Compress PDF files to the exact limit required by USCIS secure. Optimize scanned documents and certificates with zero quality loss.
To ensure your document is accepted by the United States official platform, it must meet the following strict criteria:
Disclaimer: These requirements are verified based on official guidelines. However, platform rules and guidelines can change. Always consult the official USCIS portal before final submission.
The United States Citizenship and Immigration Services (USCIS) has stringent requirements for submitting digital evidence, including I-130 supporting documents or naturalization paperwork. Very often, multi-page scanned PDF documents exceed their strict file size ceilings. Our tool optimizes these PDFs by restructuring internal elements and downsampling scanned images while ensuring the text remains perfectly crisp and legible for immigration officers.
