The United States Citizenship and Immigration Services (USCIS) is a government agency that was created in 2003 as part of the U.S. Department of Homeland Security (DHS). Prior to the establishment of the USCIS, the Immigration and Naturalization Service (INS) was responsible for managing immigration-related activities. However, after the terrorist attacks of September 11, 2001, the federal government reorganized the INS and split it into three separate agencies: USCIS, Immigration and Customs Enforcement (ICE), and Customs and Border Protection (CBP).

The USCIS is responsible for managing and processing immigration applications and petitions, as well as overseeing the naturalization process for immigrants seeking to become U.S. citizens. The agency’s main functions include:

  1. Processing visa applications: The USCIS manages visa applications for foreign nationals seeking to enter the United States for work, study, or other purposes. The agency is responsible for reviewing and adjudicating applications for a wide range of visa categories, including H-1B visas for skilled workers, L-1 visas for intra-company transferees, F-1 visas for students, and B-1/B-2 visas for tourists and business visitors.
  2. Naturalization process: The USCIS administers the naturalization process for immigrants seeking to become U.S. citizens. This includes reviewing and adjudicating applications for naturalization, conducting background checks and interviews, and administering the naturalization oath.
  3. Managing immigration status: The USCIS is responsible for managing the immigration status of foreign nationals who are already in the United States. This includes processing applications for green cards, temporary work visas, refugee and asylum status, and other forms of legal immigration.
  4. Adjudicating petitions for family-based immigration: The USCIS also reviews and adjudicates petitions for family-based immigration, including marriage and adoption cases. The agency is responsible for determining whether a petitioner is eligible to sponsor a family member for immigration, and whether the family member meets the requirements for immigration to the United States.
  5. Providing humanitarian services: The USCIS provides humanitarian services for individuals who may be at risk if they return to their home country. This includes the Temporary Protected Status (TPS) program, which provides temporary relief from deportation for individuals from countries affected by natural disasters, armed conflict, or other extraordinary conditions.
  6. Investigating and enforcing immigration laws: The USCIS also has the authority to investigate and enforce immigration-related laws and regulations. This includes conducting site visits to ensure that employers are complying with the rules for hiring foreign workers, and conducting fraud investigations to identify and prosecute individuals who may be engaging in fraudulent activities related to immigration.

In recent years, the USCIS has faced significant challenges related to processing times and backlogs. Many applicants and petitioners have experienced delays in receiving decisions on their applications, which has led to frustration and anxiety for those waiting for a resolution. Additionally, changes to immigration policies under different presidential administrations have led to uncertainty and confusion for individuals seeking to immigrate to the United States.

Despite these challenges, the USCIS remains a critical component of the U.S. immigration system. The agency plays an important role in ensuring that immigration laws are followed and that foreign nationals are able to enter and remain in the United States legally. For individuals seeking to navigate the complex world of U.S. immigration, understanding the role of the USCIS is an important first step.
