When it comes to U.S. immigration, one acronym appears more frequently than most: CIS. While today we commonly refer to the agency as USCIS (U.S. Citizenship and Immigration Services), the term CIS is still used by many people to describe the federal agency responsible for processing immigration and naturalization applications. USCIS is part of the Department of Homeland Security (DHS) and was established in 2003, following the reorganization of immigration functions after the creation of DHS.
For immigrants, families, and employers, understanding the role of CIS—or USCIS—is critical. This agency determines eligibility for green cards, citizenship, employment visas, humanitarian benefits, and much more. In many ways, it is the gateway for those seeking lawful immigration status in the United States.
This article explains what CIS is, its history, the services it provides, and why it plays such a vital role in immigration.
What Does CIS (USCIS) Do?
CIS, officially known as U.S. Citizenship and Immigration Services (USCIS), oversees the lawful immigration system of the United States. Its responsibilities are wide-ranging and affect millions of immigrants every year. Key areas of responsibility include:
- Processing Citizenship Applications: Through Form N-400, CIS administers the naturalization process for lawful permanent residents who want to become U.S. citizens.
- Managing Green Card Applications: CIS reviews and decides on immigrant petitions and adjustment of status applications that lead to lawful permanent residency.
- Overseeing Employment Authorization: From temporary work permits to permanent employment-based visas, CIS regulates whether individuals may legally work in the U.S.
- Adjudicating Humanitarian Benefits: Refugee, asylum, Temporary Protected Status (TPS), and other humanitarian relief programs are managed by CIS.
- Handling Family Immigration: U.S. citizens and lawful permanent residents can sponsor family members, and CIS is the agency that processes these petitions.
- Fraud Prevention and Background Checks: CIS conducts security checks to ensure applicants meet eligibility requirements and pose no threats to national security.
The History of CIS
Before the creation of USCIS, immigration functions were handled by the Immigration and Naturalization Service (INS). After the attacks of September 11, 2001, the U.S. government restructured its immigration services. In 2003, the Department of Homeland Security (DHS) divided the former INS into three new agencies:
- USCIS (formerly CIS) – Responsible for immigration benefits and services.
- ICE (Immigration and Customs Enforcement) – Responsible for enforcement and investigations.
- CBP (Customs and Border Protection) – Responsible for border security and customs.
This restructuring allowed CIS (now USCIS) to focus exclusively on providing immigration services without the conflicting role of enforcement.
Why CIS Matters for Immigrants
For anyone seeking a future in the United States, CIS is unavoidable. Whether you want to reunite with family, obtain work authorization, adjust your status, or pursue citizenship, CIS determines the outcome. Here’s why it matters so much:
- Gatekeeper Role: CIS decides who is eligible for key benefits like green cards and work permits.
- Family Unity: Families depend on CIS to process sponsorship petitions, which often take years.
- Career Opportunities: Foreign professionals and U.S. employers rely on CIS to approve work visas like H-1B, L-1, and O-1.
- Humanitarian Relief: CIS processes life-saving applications for refugees and asylum seekers.
Because so many lives depend on CIS decisions, accuracy and timeliness are crucial. Unfortunately, backlogs and delays have become common, which makes legal guidance even more important.
Common Applications Handled by CIS
There are hundreds of forms and applications overseen by CIS, but some of the most common include:
- Form I-130 – Petition for Alien Relative
- Form I-485 – Application to Adjust Status
- Form I-765 – Application for Employment Authorization
- Form N-400 – Application for Naturalization
- Form I-140 – Immigrant Petition for Alien Worker
- Form I-589 – Application for Asylum and Withholding of Removal
Each form has specific requirements, fees, and evidence that must be submitted. Even small errors can lead to delays or denials, making it essential to prepare thoroughly.
Challenges Applicants Face with CIS
Despite its vital role, CIS is not without challenges. Applicants often encounter:
- Lengthy Delays: Some green card and citizenship applications can take years to process.
- Complex Requirements: The rules for eligibility are detailed and change frequently.
- Strict Evidence Standards: Insufficient documentation can lead to Requests for Evidence (RFEs) or denials.
- Language Barriers: Many immigrants struggle to navigate forms that are only in English.
- Policy Changes: Immigration law is constantly evolving, which can affect eligibility and procedures.
Because of these challenges, working with an experienced attorney is often the best way to ensure success.
Tips for Navigating CIS Successfully
If you’re preparing an application with CIS, here are some important steps to follow:
- Stay Informed – Monitor official USCIS updates and the Visa Bulletin for policy changes.
- Keep Records Organized – Save copies of every form, receipt, and communication.
- Respond Promptly – If you receive a Request for Evidence, respond before the deadline.
- File Accurately – Ensure every form is completed correctly to avoid unnecessary delays.
- Consider Legal Help – An attorney can help you avoid mistakes and strengthen your application.
CIS and the Future of U.S. Immigration
CIS is central to the immigration debate in the United States. With over 20,000 employees and contractors, the agency handles millions of applications each year. As the U.S. continues to balance security concerns with its tradition of welcoming immigrants, CIS will remain at the forefront of policy changes and implementation.
Future reforms may streamline processes, increase digital access, and improve transparency. However, given the complexity of U.S. immigration law, applicants will still need to prepare carefully and seek professional advice when necessary.
