Form I-797
Notice of Action may or may not have an expiration date. It is used to notify the individual that a fee was paid, an application was accepted, the case is pending, a step in the process is completed, or status is approved. Individuals with I-797s are undocumented unless it verifies that status has been approved.
Example: An example that a step in the process has been completed but status has not been approved is the Notice of Approval for Immigrant Petition for Relative. This is the initial step in the family-related immigrant application process. It solely establishes relationship. It does not establish status. If this is the only document provided, the individual is considered undocumented for purposes of benefits eligibility.
Example: An example that status is approved is the Approval Notice of an I-360 Self-Petition under the Violence Against Women Act (VAWA). In most cases a VAWA self-petitioner will first receive a Prima Facie notice, indicating that the petitioner has submitted evidence sufficient to establish a case. Both notices verify that the individual is a qualified immigrant and their status does not expire.
