Form I-797, Notice of Action
Form I-797, Notice of Action, is issued as a result of an application or a petition submitted to the USCIS. Foreign nationals might have Form I-797 as a result of a request to change from one non-immigrant classification to another, or because a petition has been filed on their behalf by an employer or other entity. If the application or petition is approved by USCIS, a Form I-797 is issued to verify the approval.
The top left-hand corner of Form I-797 is imprinted with a unique number which begins with three letters, followed by 10 digits. This form also contains a description of the action requested and the name of the person or organization which filed the petition, the visa classification approved and the validity dates. The lower half of the form contains a replacement I-94 card.
The beneficiary of an approved Form I-797 for an employment-related "immigration status" is only permitted to work or receive compensation from the sponsoring employer listed on Form I-797.
A UNH employee in possession of a valid I-797 for an employment-authorized immigration status such as a J-1, H-1B, TN or O-1 does not need an additional employment authorization document (such as an EAD card) and need only present Form I-797 and a valid picture identification for employment verification.
