The U.S. Citizenship and Immigration Service uses Form I-797, Notice of Action, to notify applicants of actions it has taken on their cases or to request additional information. The form may include such information as a notice of petition approval, confirmation of received payments, official notice of a scheduled interview or other appointment, rejection of an application, or a request for evidence, according to the USCIS.Continue Reading
As of 2015, the USCIS uses seven versions of Form I-797, according to its website. The basic version is used to inform people when their petition or application has been approved. Form I-797A is used to provide a replacement Form I-94, and Form I-797B indicates approval of an alien worker petition.
Form I-797C usually contains information that the recipient must act upon promptly, such as a request for an interview or scheduled appointment for fingerprinting or biometric recording. The USCIS advises applicants that failure to respond to a Form I-797C can create delays in case processing, its website explains.
Other versions of the form are I-797D, which is issued in conjunction with benefit cards, and I-797E, a request to submit evidence, according to USCIS. The final version is I-797F, Transportation Letter, which the department issues overseas to authorize applicants to travel.Learn more about Immigration
