Enter your entry date to see the latest departure day for a standard 6-month admission — and learn the I-94 rules that actually control your stay.
A B1/B2 visitor visa does not set your permitted stay — the CBP officer at the border does, and the standard admission is up to 6 months (182 days) recorded on your electronic I-94. The visa in your passport can be valid for ten years, yet each individual visit is still limited by the I-94 date.
After every entry, look up your official departure deadline on the CBP I-94 website. Overstaying the I-94 — even with a valid visa — starts accruing unlawful presence: more than 180 days triggers a 3-year entry bar, more than a year a 10-year bar.
There is no written annual limit, but CBP officers scrutinize visitors who spend more time inside the US than outside. A common rule of thumb is to keep total presence under ~6 months per rolling year and to spend meaningful time abroad between visits. Spending 5–6 months, leaving for two weeks and returning is a classic pattern that leads to secondary inspection and refused entry.
Even as a tourist you can accidentally become a US tax resident under the Substantial Presence Test: 183 points, counting all days this year, ⅓ of last year's days and ⅙ of the year before. Long snowbird stays hit it faster than people expect — track your days and see the 183-day tax residency calculator.
Each entry is typically granted up to 6 months (182 days), decided by the CBP officer and recorded on your I-94. The visa validity itself does not define the length of stay.
Yes, you can file form I-539 with USCIS before your I-94 expires. Approval is discretionary; remaining while a timely application is pending is generally tolerated.
Unlawful presence starts accruing: over 180 days leads to a 3-year entry ban, over one year to a 10-year ban, and the visa is automatically voided.
