F-1 Grace Period Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- Estimated grace period end date = completion date + grace period days. Days until planned action = planned action date - completion date.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Completion Date: 2026-05-15
- Grace Period: 60 days
- Planned Action Date: 2026-07-01
Expected outputs
- Estimated Grace Period End Date: 2026-07-14
- Days from Completion to Planned Action: 47 days
- Planned Action Status: On or before estimated grace period end
Known limitations
- This calculator does not determine SEVIS status, transfer eligibility, change-of-status eligibility, reentry options, unemployment limits, reinstatement, or USCIS action.
Assumptions
- The grace period is modeled as calendar days added to the completion date.
- The grace period day threshold is entered by the user and defaults to 60 days for planning.
- This is a planning estimate only, not legal advice, not an official immigration, travel, school DSO, USCIS, CBP, consulate, employer, or government determination.

- Completion Date accepts calendar dates.
- Grace Period accepts values in days.
- Planned Action Date accepts calendar dates.
- Days from Completion to Planned Action is displayed in days.
Rounding rules
