The 3-year and 10-year bars
Under INA §212(a)(9)(B), accruing unlawful presence in the United States creates bars to future admissibility. Unlawful presence is generally the time after your authorized stay expires (as shown on your I-94) that you remain in the US without lawful status. The bars trigger when you depart: if you accumulated between 180 days and 1 year of unlawful presence, you are inadmissible for 3 years; if you accumulated 1 year or more, you are inadmissible for 10 years.
Crucially, these bars do not apply while you are inside the United States — they are triggered only upon departure. This means a person who has overstayed for 2 years and wants to apply for a green card through a US citizen spouse is in a difficult situation: adjusting status inside the US may avoid the bar (if eligible), but any departure to attend a consular interview triggers the 10-year bar. A waiver (Form I-601) is required to overcome the bar at a consulate.
ESTA and visa application consequences
Any US visa overstay — even a single day past your I-94 expiration — disqualifies you from future travel to the US under the Visa Waiver Program (ESTA). You must apply for a B-2 tourist visa instead, where the overstay history will be heavily scrutinized. Lying about a prior overstay on a DS-160 or ESTA application constitutes willful misrepresentation (INA §212(a)(6)(C)), a separate ground of inadmissibility with lifetime consequences.
Exceptions to unlawful presence accrual
Not all time in the US without authorization counts as unlawful presence for bar purposes. Exceptions include: minors (under 18) do not accrue unlawful presence; pending asylum applicants do not accrue unlawful presence while their application is filed in a timely manner; pending I-539 filers (extension of stay) in authorized status do not accrue unlawful presence until the petition is denied; battered immigrants and survivors of trafficking have specific protections. DACA holders' unlawful presence accrual is a complex, ongoing legal question as of 2026.
Related Questions
If I overstay by just a few days, is there still a bar?
A few days of overstay does not trigger the 3-year or 10-year bar (those require 180+ days). However, even short overstays appear in CBP records and will adversely affect future visa applications and CBP entry decisions.
Can I apply for a green card from inside the US if I've overstayed?
Immediate relatives of US citizens (spouse, parent, unmarried minor child) may be able to adjust status in the US without triggering the departure bar, depending on their specific history. Non-immediate-relative categories generally cannot avoid the bar.
What is an I-601A provisional waiver?
An I-601A allows immediate relatives of US citizens (and certain LPRs) to apply for an unlawful presence waiver from inside the US before departing for a consular interview. If approved, they get advance permission to re-enter despite the bar, minimizing separation time. It is not available for all waiver bases.
Does time on OPT count toward unlawful presence?
No. OPT is authorized status — time on a valid EAD during OPT does not accrue unlawful presence even though the visa stamp may have expired.
Can I leave and re-enter while on OPT if I've never overstayed?
Yes. With a valid F-1 visa, a DSO-endorsed I-20, and your EAD, you can travel internationally during OPT. You must have a valid F-1 visa stamp in your passport for re-entry (or apply for a new visa at a consulate abroad before returning).
