How the I-94 Expiration & Unlawful Presence Calculator works
The I-94 Expiration & Unlawful Presence calculator tracks the admit-until date printed on a nonimmigrant's I-94 arrival/departure record and projects the two federal unlawful-presence thresholds that follow if someone remains in the US past that date: the 180-day bar and the 1-year bar, both of which can trigger multi-year reentry bans once the person departs the country.
Unlawful presence accrual generally begins the day after the I-94 admit-until date passes (for those admitted until a specific date, as opposed to "duration of status" admissions, which follow different accrual rules entirely). Accruing more than 180 days of unlawful presence before departing triggers a 3-year bar on reentry under INA § 212(a)(9)(B); accruing a full year or more triggers a 10-year bar — both measured from the date of departure, not the date the bar was accrued.
The I-94 admit-until date is not always the same as a visa's expiration date — a visa can remain valid while the I-94 has already expired, and it is the I-94 date, not the visa date, that controls how long someone may remain in the US on a given entry.
Worked example
An I-94 shows an admit-until date of April 1. Unlawful presence would begin accruing April 2 if the person remains past that date. The 180-day mark — the threshold for the 3-year reentry bar — falls on September 28. The 1-year mark — the threshold for the 10-year bar — falls on the following April 2.
Frequently asked questions
Does overstaying automatically trigger the reentry bar the moment I hit 180 or 365 days?
No — the bar is triggered by departing the United States after having accrued more than 180 days (for the 3-year bar) or 1 year or more (for the 10-year bar) of unlawful presence. Someone who overstays but never departs does not trigger the bar on that basis alone, though they accumulate other serious immigration consequences the longer they remain out of status.
What if my I-94 says "D/S" instead of a specific date?
"Duration of status" admissions (common for F-1 students and J-1 exchange visitors) do not have a fixed expiration date and follow different rules for when unlawful presence begins to accrue — typically only after a formal finding by USCIS or an immigration judge. This calculator, which requires a specific admit-until date, does not apply to D/S admissions.
Is this immigration advice?
No — this is general information based on INA § 212(a)(9)(B), not legal advice for a specific case. Unlawful presence rules interact with waivers, adjustment of status, and other relief in ways that are highly fact-specific. Consult an immigration attorney well before any of these dates if there is any uncertainty about status.
