The United States Citizenship and Immigration Service (USCIS) is a part of the Department of Homeland Security. Formerly, the Immigration and Naturalization Services, under the direction of the Department of Justice, supervised immigration issues. The change occurred in 2003 as part of the Homeland Security Act. The Form I-797C is one of the notices the USCIS uses for three purposes.
Receipt of Application
The USCIS may send Form I-797C to acknowledge an application has been received. The form may contain information regarding the next steps the applicant must take. It may also serve as a receipt for the payment of fees included with the application.
The Form I-797C may be used to notify an employer or other petitioner of an action pertaining to a beneficiary. The beneficiary may be a nonimmigrant employee or a member of the petitioner's family, or the beneficiary may be the applicant himself. The petitioner may be the employer, a family member residing in the United States or the applicant.
If the USCIS denies or rejects the application, it may also use Form I-797C to notify the applicant. The denial may result from an applicant's failure to meet immigration requirements but may also result from a failure to enclose the appropriate fees or supporting documentation.
