What USCIS Application Support Centers Are and How They Function

USCIS Application Support Centers (ASCs) are physical locations across the United States where people can submit documents, take biometric photos, and complete certain steps in their immigration processes. These centers operate under the U.S. Citizenship and Immigration Services, a division of the Department of Homeland Security. Understanding what happens at these centers can help you learn about the different ways USCIS collects information from people going through various immigration procedures.

As of 2024, USCIS operates more than 200 Application Support Centers located in major cities and smaller communities throughout all 50 states. These facilities are not the same as USCIS field offices, where immigration officers make decisions about cases. Instead, ASCs function as collection points for biometric data—mainly fingerprints and photographs—and as places where people can submit supporting documents for their cases. Some centers also handle certain document collection tasks that are part of specific immigration processes.

The primary function of ASCs involves biometric services. During a biometric appointment, staff members take your fingerprints using digital scanning technology and photograph you for your case file. This information is used for background checks and identity verification. USCIS schedules biometric appointments as part of many different immigration processes, including those for people seeking to renew certain documents, people going through security clearance procedures, and people participating in various visa categories.

Each ASC operates during regular business hours, typically Monday through Friday, with some locations offering limited Saturday hours. The facilities are staffed by USCIS personnel and contractors trained specifically to handle biometric collection and document intake. Wait times vary significantly depending on location and time of year, with some centers experiencing waits of 15 minutes or less and others potentially having longer periods during peak seasons.

Practical Takeaway: If you receive a notice from USCIS requiring you to visit an Application Support Center, the notice will specify which center location you should visit and when. The notice will explain what documents or steps you need to complete at that visit.

Locating Your Nearest Application Support Center and Understanding Appointments

Finding your assigned Application Support Center location requires using the official USCIS website. USCIS does not assign people to centers randomly; instead, they typically assign you to the center closest to your residence or the address listed on your case. The USCIS website contains a searchable directory of all Application Support Centers with their addresses, phone numbers, and hours of operation organized by state and city.

To locate an ASC, you can visit the USCIS.gov website and use their "Find a USCIS Office" tool. This tool allows you to search by zip code or city name. The results will show you the nearest Application Support Centers, their complete contact information, and their operating hours. Some states with larger populations have multiple centers to serve different geographic areas. For example, California has more than 20 Application Support Centers, while less populated states may have only one or two.

When USCIS requires you to visit an Application Support Center, they will send you a written notice—typically called a "Notice of Biometric Services Appointment" or similar document. This notice will include several critical pieces of information: the specific ASC location you must visit, the date and time of your appointment, what documents to bring, and what to expect during your visit. The notice will explain that you should not arrive more than 15 minutes before your scheduled appointment time. Arriving significantly early will not move up your appointment and may cause confusion at the center.

USCIS appointment notices specify which documents you must bring. These often include your notice itself (bring the original or a copy), a valid government-issued photo ID, and your USCIS receipt number if you have one. Some notices request additional documents depending on your specific case type. The notice will clearly list these requirements. Bringing only what the notice requests, rather than a large stack of documents, helps the process move more smoothly.

If you cannot attend your scheduled appointment due to circumstances beyond your control, you should contact the Application Support Center directly using the phone number on your notice. Explain your situation and ask about rescheduling. USCIS generally allows rescheduling for reasonable cause. However, missing an appointment without contacting USCIS beforehand may result in your case being delayed or your application being denied, depending on your case type.

Practical Takeaway: Keep your appointment notice in a safe place and review it carefully at least one week before your scheduled visit. Verify the date, time, and location, and gather the required documents ahead of time rather than the day of your appointment.

What to Expect During Your Application Support Center Visit

Understanding the typical sequence of events during an Application Support Center visit can reduce stress and help you prepare properly. Most visits follow a similar pattern, though specific steps may vary slightly depending on your case type. When you arrive at your scheduled appointment time, you will check in at the reception area. Staff members will verify your appointment notice and ask to see your identification. They may ask you to confirm your name, date of birth, and case receipt number.

After check-in, you may wait in a waiting area until a biometric services officer calls your name. The actual biometric collection process typically takes 10 to 20 minutes. During this time, the officer will conduct a brief interview to verify your identity and confirm information from your case. They will explain the biometric process and ask you questions to verify that you are the correct person for the appointment. Having your identification readily available makes this step faster.

The fingerprinting process uses modern digital technology rather than the traditional ink-and-paper method. You place each finger on a digital scanner, one at a time. The officer will guide you through this process. If the scanner does not capture a clear print, the officer will ask you to try again. This is normal and is not a sign that anything is wrong. Digital systems sometimes require multiple attempts, especially if someone's fingerprints are less distinct due to age, occupational wear, or other factors. The entire fingerprinting process for all 10 fingers typically takes less than 10 minutes.

After fingerprinting, the officer will take a digital photograph for your file. You will be asked to sit in front of a camera, remove any hats or sunglasses, and look directly at the camera. The photo is used for identity verification purposes and to maintain your file with USCIS. The photograph requirements are relatively straightforward—a clear, straight-on view of your face is all that is needed.

If your appointment notice indicated that you should submit supporting documents, you will hand these to the officer or to a document intake specialist. The officer will review your documents to ensure they match your case information and that you have provided everything the notice required. The officer will typically make a copy of your documents and return the originals to you, or the notice will explain whether originals should be left at the center. Always keep copies of everything you submit.

At the conclusion of your visit, the officer will provide you with information about what happens next. For most people, a receipt or confirmation will be provided showing that biometric services were completed. You will be told approximately when to expect a decision on your case or when your next step will occur. Do not expect to receive a decision or approval during your visit—the biometric information must be processed and reviewed before any decision is made.

Practical Takeaway: Plan to arrive about 10 minutes early, bring all required documents organized in the order listed on your notice, wear clear, readable identification, and expect the entire visit to take between 30 and 60 minutes including wait time.

Document Requirements and What to Bring to Your Appointment

Your USCIS appointment notice will specify exactly which documents you must bring. These requirements vary depending on your case type, but certain documents are nearly always required. Always bring your original appointment notice or a clear copy of it. USCIS staff use this document to locate your case in their system and verify your appointment details. Without your notice, staff may be unable to process your visit, and you may be asked to reschedule.

A valid government-issued photo identification is mandatory at every Application Support Center visit. Acceptable forms of ID include a passport, driver's license, state ID card, military ID, or similar document issued by a government agency that includes your photograph and signature. The ID must not be expired or so worn that your photograph is no longer recognizable. If your ID is in a language other than English, bring a certified English translation along with the original. Some centers may accept other forms of ID in limited circumstances, so if you do not have one
