The US Citizenship and Immigration Services (USCIS) is a government agency responsible for overseeing lawful immigration to the United States. Its primary function is to process and adjudicate applications for various immigration benefits, such as green cards, work permits, and naturalization. USCIS provides a public developer portal (developer.uscis.gov) with APIs for case status lookup and FOIA request submission. The Torch API Program enables qualified software developers to integrate USCIS services into immigration case management applications, providing OAuth 2.0 secured access to case status information and Freedom of Information Act (FOIA) request capabilities.
