The Date Calculator for Immigration Processing was a Knowledge Community for International Student and Scholar Services (KCISSS) resource developed to assist advisors in determining "validation report" deadlines. The tool was last revised in 2010. The date calculators in this tool (a series of Excel spreadsheets in one file) calculate the number of days, years or months of eligibility remaining for a particular immigration benefit; or determine which day a particular deadline falls for filing a petition or application.
The Date Calculator provides basic calculations that will point foreign student and scholar advisers in the right direction. NAFSA disclaims any and all liability resulting from reliance upon this information, and individual advisers, applicants, and petitioners remain fully responsible for calculating filing date requirements. Likewise, use of the Date Calculator should not be construed as legal advice or expert assistance.
