EVUS and the I-94 (10-year B1/B2 Chinese passport holders)

EVUS is a mandatory pre-travel enrollment for holders of a 10-year B1/B2 U.S. visa in a mainland Chinese passport. It is not a visa, not ESTA, and does not change the I-94 — but without a valid EVUS you cannot board a flight to the U.S.

Direct answer

EVUS (Electronic Visa Update System) is a CBP pre-travel enrollment required for holders of a 10-year B1/B2 visa in a mainland Chinese passport. It is not a visa and not ESTA. Valid for 2 years or until the passport / visa expires, whichever comes first. Official site: evus.gov. No valid EVUS → no boarding. A valid EVUS does not change the I-94 — COA is still B1/B2, and the Admit Until Date is set by CBP at the port (usually up to 6 months).

What EVUS actually is

Introduced in 2016, EVUS applies to mainland Chinese passport holders with a 10-year B1, B2, or B1/B2 U.S. visa. The rationale: because the visa is valid so long, CBP wants updated traveler information before each entry.

  • Official site: evus.gov (only). Watch out for lookalike scam sites.
  • Fee: currently free (a fee has been discussed historically; check the official site).
  • Validity: 2 years, or until the passport or visa expires — whichever comes first.
  • Re-enroll triggers: new passport, new visa, name / gender change, material employment change.

EVUS is not a visa, and not ESTA

  • Not a visa: the visa is still the consulate-issued foil in your passport. EVUS is supplemental self-reported info.
  • Not ESTA: ESTA is for VWP nationals (mainland China is not in VWP). Two entirely separate systems.
  • Does not change the I-94: after admission the I-94 shows COA = B1/B2, with the standard Admit Until Date set by CBP (usually up to 6 months).

When to re-enroll

  1. Prior EVUS is past 2 years or about to expire.
  2. You have a new passport (even if the old visa was transferred).
  3. You have a new 10-year B1/B2 visa.
  4. Name, gender, or nationality changed.
  5. Significant employment change (new employer, new industry).

Complete EVUS at least 72 hours before departure to leave room for occasional manual review.

How EVUS connects to the I-94

  1. Before boarding — the airline checks EVUS validity; no valid EVUS = no boarding.
  2. At the U.S. port — CBP reviews visa, purpose of travel, and decides admission.
  3. On admission — I-94 is created (COA = B1/B2, Admit Until Date usually up to 6 months).
  4. After entry — EVUS status is irrelevant to your authorized stay; you follow the Admit Until Date.

Common misconceptions

  • "EVUS is an extended visa." No — the visa's validity is set by the consulate.
  • "If EVUS expires I must leave the U.S. now." No — it only affects the next entry.
  • "EVUS-approved = admission guaranteed." No — CBP can still refuse at the port.
  • "F-1, H-1B, L-1 also need EVUS." They do not — EVUS only covers 10-year B1/B2 Chinese passports.
  • "With EVUS I can stay past 6 months." No — the Admit Until Date is the only limit.

Frequently asked (FAQ)

Is EVUS a visa?

No. EVUS (Electronic Visa Update System) is a CBP information update requirement for 10-year B1/B2 Chinese-passport holders. The visa itself remains the foil in the passport.

Is EVUS the same as ESTA?

No. ESTA is for VWP nationals (mainland China is not in VWP). EVUS is a separate system exclusively for 10-year B1/B2 Chinese-passport holders.

What happens if my EVUS expires?

Airlines will deny boarding at check-in. It does not affect your current authorized stay if you are already in the U.S., only your next entry.

Does EVUS change my I-94 COA or length of stay?

No. CBP still admits you as B1/B2 with the standard Admit Until Date (usually up to 6 months). EVUS is a pre-entry authorization only.
