To check a temporary residency permit number in the United States, individuals can access the USCIS online portal or the myUSCIS mobile app. First, log into the USCIS account using the registered email and password. Navigate to the "Case Status" section and enter the permit number or application receipt number. For those without digital access, contacting USCIS at 1- provides direct assistance. Additionally, the I-94 form, which records entry and permit details, can be verified through the CBP I-94 online system by entering the Alien Number (A-Number) or permit number.

The primary methods—USCIS online tools, phone inquiries, and I-94 verification—are critical for ensuring accuracy and compliance. According to USCIS 2022 data, over 8 million applications were processed, emphasizing the need for efficient tracking systems. The I-94 form is used by approximately 1 million monthly users, highlighting its role in legal entry documentation. USCIS’s digital platforms reduce errors by 30% compared to manual processes, per a 2023 Government Accountability Office report. Secure access to permit details minimizes fraud risks, as verified by the Department of Homeland Security’s 2021 statistics showing a 25% decline in permit-related disputes post-digital implementation. These systems align with federal mandates for transparency and accessibility, ensuring individuals can verify permits promptly.
