How this calculator works

For each trip, the estimate counts calendar days from departure date to return date and excludes the return date. Invalid or blank trip rows count as zero days.
Total days outside = sum of max(return date - departure date, 0) for each entered trip. Days before threshold = threshold - total days outside.

Inputs explained

Departure dates

The dates you left the United States for each trip.

Return dates

The dates you returned to the United States. This model excludes the return date from outside-day counting.

Planning threshold

A user-entered day limit for your own comparison. It is not an official eligibility rule unless you confirm that rule separately.

Understanding your results

The primary result is the estimated total days outside the U.S. Compare it with your own threshold, then verify the official counting method before relying on it.

Example scenarios

Two-trip travel log

A March 1 to March 11 trip counts as 10 days outside, and a June 5 to June 20 trip counts as 15 days, for 25 total estimated days outside.

Things to Keep in Mind

Tips & Best Practices

  • Compare results with passport stamps, I-94 travel history, tickets, and employer or school records.
  • Keep a conservative buffer when a travel threshold matters.
