For people who have filed applications with the United States Citizenship and Immigration Services, getting mail in from the agency can bring good news or challenging news. Knowing how to interpret the information presented in the written mail from them can be difficult. One form that our readers in Arizona might come across at some point during their dealings with the USCIS is the Form I-797. This form serves various purposes, depending on which version you receive.
The Form I-797C is one of the first ones a person might get. This form, which is a Notice of Action form, is sent out to acknowledge receipt of payments, transfer of files, reopening of cases, rejection of application or a notice of an appointment. The appointment can be for a fingerprint biometric, an interview or a rescheduled appointment.
The Form I-797-E is another Notice of Action. This one is used to request that you submit evidence.
The Form I-797 is sent out to let you know that your application has been approved. If the petition was for an alien worker, the approval will be sent via a Form I-797B. When the application is approved, benefit cards might be issued. Those cards would have a Form I-797D with them.
There are two other versions of the form. A Form I-797F is given to an applicant overseas as permission to travel. A Form I-797A is given to an applicant to replace a Form I-94.
Some of these I-797 forms might have instructions that outline action you need to take. Fully understanding what you need to do is vital to ensure that you don't jeopardize your application or petition.
