Overview
- B‑1/B‑2 visitors may request more time by filing Form I‑539 (with I‑539A for dependents) before the I‑94 expires, with USCIS recommending about 45 days’ lead time.
- CBP officers set the initial stay recorded on the I‑94—commonly up to 180 days per entry—so that date controls the extension deadline.
- Recent coverage cites filing fees of about $420 online or $470 by mail, and applications should include the I‑94, valid passport/visa, a clear reason for the extension, proof of funds, and evidence of intent to depart.
- Timely filings preserve lawful status while USCIS decides, but certain categories (such as C, D, K, S, WT, WB) are ineligible and violations like unauthorized work can trigger denial and future entry problems.
- Green‑card holders may reenter with an expired card if they show an I‑797C renewal receipt or other accepted proof (e.g., ADIT stamp), while longer absences require planning such as a reentry permit (I‑131) or, after two years away, an SB‑1 returning resident visa.
