The US Three-Year and Ten-Year Bars: How an Overstay Becomes a Ban

In the United States, staying beyond the date you were admitted until does more than create a problem on the way out. Under US law, an overstay of a certain length, followed by departure, triggers an automatic bar on returning. Here is how it works.

What is unlawful presence?
Time spent in the United States after the period of stay you were admitted for has ended, or without having been admitted at all. It is counted in days.

What triggers the three-year bar?
More than 180 days of unlawful presence, but less than one year, followed by departure from the United States. The traveller is then barred from returning for three years.

And the ten-year bar?
One year or more of unlawful presence, followed by departure. The bar lasts ten years.

Why does leaving trigger it?
Because that is how the law is written. The bar applies to someone who departs after accruing the unlawful presence. People are often surprised that it is the departure, not the overstay itself, that starts the clock on the ban.

Is the bar automatic?
Yes. It applies by operation of law. There is no hearing required for it to take effect. Some waivers exist in limited circumstances, but they are not routine and require a separate application.

What about shorter overstays?
An overstay of 180 days or less does not trigger the three-year bar, but it is not harmless. It is recorded, it can make a traveller ineligible to use the Visa Waiver Program in future, and it will be relevant to any later visa application.

How does it affect future applications?
US visa application forms ask about previous overstays and immigration violations. So do applications for travel authorisations to the United States and to many other countries. An overstay recorded in the US system is visible to US consular officers, and the honest answer has to be given every time.

What should I do?
Know the date your permitted stay ends. It is set when you are admitted, not by your visa's expiry date, which is a different thing. If your plans change, seek to extend before that date, not after.

If you have already overstayed, get advice from a qualified immigration lawyer before you make any decision about leaving.
