Scope and purpose
The I-94 records admission or parole information and, where applicable, the authorized period of stay. It is not the same document as a visa, and a visa’s expiration date does not necessarily establish the permitted stay.
Related rules and practical context
Retrieve and review the CBP record and seek correction through the appropriate official process if it contains an error. Admission, parole and unlawful presence are different legal concepts. Form I-485 eligibility can depend on entry facts, not simply possession of a visa.
