U.S. Citizenship and Immigration Services

Introduction to U.S. Citizenship and Immigration Services

The U.S. Department of Homeland Security (DHS) oversees the U.S. Citizenship and Immigration Services (USCIS). It is in charge of handling various immigration-related applications as well as managing and enforcing the country’s immigration laws. In the immigration system, USCIS is essential since it processes applications for visas, green cards, naturalization, and other immigration benefits.

Understanding USCIS:

The primary responsibility of USCIS is to process and decide immigration-related petitions and applications. Only those who qualify will receive immigration privileges like legal permanent residence (green cards) or American citizenship. By conducting background investigations and screening candidates for immigration benefits, the agency also contributes to preserving national security.

History of USCIS:

As part of the Immigration and Naturalization Service (INS) reform, USCIS was founded on March 1, 2003. In order to better serve applicants, USCIS was established to divide the immigration enforcement and service functions. Since that time, USCIS has been the main organization in charge of managing immigration benefits and services.

USCIS Services and Benefits:

For those looking for help with immigration-related matters, USCIS provides a wide range of services and advantages. Key advantages and services offered by USCIS include:


  • processing of applications for green cards (permanent residence)

USCIS Forms and Applications:

To apply for various immigration benefits, individuals are required to complete and submit specific forms to USCIS. These forms vary depending on the type of benefit being sought. USCIS forms can be downloaded from the official USCIS website or requested by mail. Each form has detailed instructions on how to complete and submit it along with the required supporting documentation.


USCIS charges fees for most of its services and benefits. The fees associated with immigration applications and petitions vary depending on the type of benefit being sought. USCIS regularly updates its fee schedule, so it is essential to check the current fees before submitting an application. Fee waivers are available for certain individuals who meet specific eligibility criteria and can demonstrate financial hardship.

USCIS Offices and Locations:

USCIS has multiple field offices and service centers located throughout the United States. These offices are responsible for processing immigration applications and conducting interviews. Additionally, USCIS operates international offices and maintains overseas presence in certain countries. Applicants can find the nearest USCIS office or service center using the USCIS website or by contacting the USCIS National Customer Service Center.

USCIS Processing Times:

The processing times for USCIS applications vary depending on the type of benefit being sought, the volume of applications received, and other factors. USCIS provides estimated processing times on its website for different types of applications. These estimates give applicants an idea of how long it may take for their applications to be processed. However, actual processing times can vary, and some applications may take longer than the estimated timeframes.

Common USCIS Issues and How to Resolve Them:

While USCIS strives to provide efficient and accurate services, applicants may encounter issues or delays during the immigration process. Some common issues include application denials, requests for additional evidence, or long processing times. To resolve these issues, applicants can contact the USCIS National Customer Service Center, seek assistance from an immigration attorney, or contact the USCIS Ombudsman’s Office, which helps individuals navigate the USCIS process.


USCIS plays a vital role in administering immigration benefits and services in the United States. Understanding the functions, services, and processes of USCIS is crucial for individuals seeking immigration benefits. By familiarizing themselves with USCIS procedures, applicants can navigate the immigration system more effectively and increase their chances of obtaining the desired immigration status.
