USCIS Application Support Center (ASC): Biometrics Guide & Rescheduling Rules

A USCIS Application Support Center (ASC) is an office run by U.S. Citizenship and Immigration Services (USCIS) where you go to give your biometrics: your fingerprints, a photo and a digital signature. USCIS uses them to confirm who you are, run background checks and make cards like your work permit and green card.

For EB-3 workers, the most important point is this: you only go to an ASC if you are applying for your green card from inside the United States. That path is called adjustment of status. If you are getting your EB-3 visa at a U.S. embassy or consulate abroad, you do not go to an ASC. Your fingerprints are taken at the consulate instead.

This guide explains who goes to an ASC, what your appointment notice means, what to bring, what happens inside, how to reschedule and what comes next.

What Is an Application Support Center?

An ASC is a USCIS office with one job: collecting biometrics. There are ASCs across the United States and its territories. You don’t pick one. USCIS assigns you an ASC based on the address it has on file for you.

What Are Biometrics?

At an ASC, “biometrics” means three things:

• Fingerprints
• A photograph
• A digital signature

The law lets USCIS require biometrics from any applicant, petitioner, sponsor or beneficiary in a case (8 CFR 103.2(b)(9)).

What Does USCIS Use Them For?

USCIS uses your biometrics to:

• Confirm your identity, so the person in the file is really you
• Run background and security checks, including FBI fingerprint checks
• Make your cards. The photo and signature go on your Employment Authorization Document (EAD) if you filed Form I-765, and on a replacement green card if you filed Form I-90.

ASC vs. USCIS Field Office

People often mix these up. They are different offices with different jobs.

	Application Support Center (ASC)	USCIS field office
Main job	Biometrics only	Interviews and in-person appointments
Example for EB-3	Fingerprints for your I-485	Your green card interview, if USCIS schedules one
Do they decide your case?	No	Officers there may decide or review it

Do EB-3 Workers Go to an ASC?

It depends on where you are when you apply for your green card.

Yes, if you are adjusting status inside the U.S. You file Form I-485, the green card application. Many people file it together with Form I-765 for work permission and Form I-131 for travel permission. USCIS then sends you a biometrics appointment. This is the path for workers already in the U.S. in valid status, for example H-2B workers moving to EB-3 or F-1 students moving to EB-3.

No, if you are outside the U.S. Most EB-3 workers who live abroad use consular processing. You file the DS-260 after the National Visa Center (NVC) opens your case, then go to an interview at a U.S. embassy or consulate. The State Department says “ink-free, digital fingerprint scans” are taken as part of the immigrant visa interview process. You never visit an ASC. To get ready for that step, see our guide to EB-3 visa interview questions.

Not during your employer’s steps. There is no ASC visit for PERM labor certification or for the I-140 petition. Those are filed by your employer.

Here is where the ASC fits if you are adjusting status:

1. PERM labor certification (employer, Department of Labor)
2. I-140 petition (employer, USCIS)
3. Wait until your priority date is current
4. File the I-485 (plus I-765 and I-131 if you want them)
5. ASC biometrics appointment
6. Possible interview at a field office
7. Green card decision

For the full picture, see the EB-3 visa process.

Your ASC Appointment Notice (Form I-797C)

USCIS tells you about your appointment with Form I-797C, Notice of Action. It lists the date, the time and the address of your ASC. If you have a USCIS online account, you can also see it there.

How long after filing does it come? It is often a few weeks after USCIS receives your application, but it varies by office and workload. Don’t treat any number as a promise.

A few things to know:

• You may get more than one notice. If USCIS sends separate notices, bring all of them.
• Keep your address current. USCIS mails notices to the address it has on file. If you move, update your address with USCIS right away. A notice that arrives late or never arrives counts as a good reason to reschedule.
• Each family member usually gets their own notice. Your spouse and children on the I-485 each have their own appointment.
• Watch for scams. USCIS does not charge to book or “speed up” a biometrics appointment. If someone offers to get you an earlier slot for money, say no.

What to Bring to Your Biometrics Appointment

USCIS asks you to bring:

• Your I-797C appointment notice. Bring every notice if you received more than one.
• A valid photo ID, such as your passport, green card or driver’s license. Make sure it is not expired.
• A copy of your filing (paper or saved on your phone). Review it before you go. USCIS says it cannot give you a copy at the appointment.
• Someone to translate, if you need one. If you don’t understand spoken English, USCIS says to bring a person who can translate for you. USCIS also has language help documents you can read beforehand.

Your attorney does not need to come with you.

One limit to know: you cannot change your name or other personal details at the ASC. Those changes go through USCIS separately.

What Happens at the ASC

The visit is simple. In most cases it goes like this:

1. Check in with your notice and photo ID.
2. Wait until staff call you.
3. Fingerprints are scanned digitally.
4. Photo is taken.
5. Digital signature is collected.
6. You leave. There is no interview and no decision on your case at the ASC.

The Digital Signature

This step matters more than it looks. USCIS says your digital signature confirms, under penalty of perjury, that your filing was complete, true and correct. That is why you should read your copy of the application before you go. If something is wrong, talk to your attorney before the appointment.

How Long Does It Take?

The fingerprints and photo themselves are quick. Most of the time is waiting. USCIS does not publish an official length, so plan for part of a day, not a few minutes, especially at busy offices.

Children

Applicants 14 and older must sign. Children under 14 don’t have to sign, but they may if they are able. A parent or legal guardian can sign for them. See dependents in the EB-3 process for how family members fit into your case.

Can I Walk In Early or on a Different Day?

Don’t plan on it. USCIS’s guidance tells you to attend the appointment on your notice. Some people report being seen early at some offices, but that is up to the office and it is not a right. The safe choice is to go on the date and time on your notice, or to reschedule properly.

How to Reschedule a Biometrics Appointment

Life happens. You can reschedule, but you must follow the rules.

Online

Since June 28, 2023, you can reschedule most biometrics appointments online through your USCIS online account. This works even if you filed on paper. You cannot use the online tool if:

• Your appointment is less than 12 hours away
• It has already been rescheduled two or more times
• The appointment date has already passed

By Phone

Call the USCIS Contact Center at 800-375-5283 (TTY 800-767-1833). Help is available in English and Spanish. If your request is late, the phone is your only option. USCIS does not accept late requests by mail, in person or online.

You Need “Good Cause”

You must ask before your appointment and show a good reason. USCIS lists examples like:

• Illness or a medical appointment
• Travel you planned before you got the notice
• Major life events, such as a wedding, funeral or birth
• Transportation problems
• Not being able to get time off work, or caregiving duties
• A notice that arrived late or never arrived

If You Miss It Without Rescheduling

Warning: If you don’t show up and don’t ask to reschedule in time with good cause, USCIS may not give you a new appointment. It may treat your application as abandoned and deny it.

For an EB-3 worker, a denied I-485 is a serious problem. It can also take down the work permit and travel permission that depend on it. If you can’t go, reschedule. Don’t just skip it.

Too Sick to Travel?

If you have a serious, ongoing medical condition that keeps you at home or in a hospital, you may qualify for a mobile or homebound appointment. Follow the instructions on your notice. You can also ask for disability accommodations online or by calling the Contact Center.

What Happens After Your Biometrics Appointment

Biometrics is one small step in a long green card case. Here is what usually follows:

• Background checks run. USCIS uses your fingerprints for FBI and security checks. You don’t need to do anything.
• Your case status may update. Check your USCIS online account or case status page.
• Your work permit and travel document can be made. If you filed an I-765, USCIS uses your photo and signature to produce your EAD card. If you filed an I-131, the same goes for your travel document. One recent change: since October 30, 2025, EAD renewals no longer get an automatic extension while they are pending, so file any renewal early.
• Your I-485 moves to review. USCIS may schedule an interview at a field office, or it may decide without one.
• Your priority date still matters. Your green card can only be approved while your priority date is current. See EB-3 visa processing times for realistic timing.

What if my fingerprints couldn’t be read? Worn or damaged fingerprints are common in manual work. USCIS may send you a second notice to try again. That is not a denial. Just go to the new appointment.

Be honest with yourself about timing. Getting your biometrics done does not mean a decision is coming soon.

Biometrics Fees

Since April 1, 2024, USCIS does not charge a separate biometrics fee for most forms. The cost is now built into the main filing fee. For example, the I-485 filing fee is $1,440, and there is no extra biometrics charge on top of it.

A separate $30 biometrics fee still applies only in a few situations, such as Temporary Protected Status (TPS) and certain immigration court cases. Those are not EB-3 cases.

Who pays? Your employer must pay the costs of PERM labor certification. That is the law (20 CFR 656.12). I-485 fees are usually the worker’s own cost unless your employer agrees to cover them. See our EB-3 visa cost breakdown for the full picture.

And again: never pay anyone just to book an ASC appointment.

Proposed 2025 Biometrics Rule: What Could Change

On November 3, 2025, the Department of Homeland Security (DHS) proposed a rule to expand USCIS biometrics (90 FR 49062). The proposal would:

• Remove the under-14 age exemption, so children of any age could need biometrics
• Add new types of biometrics, such as iris images, voice prints and, in some cases, DNA to prove family relationships
• Collect biometrics periodically from people who already have an immigration benefit, such as green card holders, until they become citizens
• Collect biometrics from some U.S. citizens who sponsor or sign immigration filings

This rule is not in effect. Public comments closed on January 2, 2026. The federal regulatory agenda lists a final rule target of December 2026. Until a final rule is published, the rules described on this page still apply.

If it is finalized, EB-3 families could see more ASC visits, including for young children. We will update this page if that happens.

Finding Your ASC

You can’t choose any ASC you like. USCIS assigns one based on your address, and it is printed on your I-797C notice.

To look up an ASC’s location and hours, use the official USCIS Office Locator. It covers every city, so searches like “application support center Orlando” or “ASC Brooklyn” are best answered there. We don’t list addresses on this page because office details change.

Common ASC Problems and Fixes

The Notice Never Arrived

Check your USCIS online account first. Then make sure your address with USCIS is correct, and call the Contact Center. A missing notice counts as good cause to reschedule.

Your ID Is Expired or the Name Doesn’t Match

Bring a valid, unexpired photo ID. Name changes can’t be made at the ASC, so contact USCIS or your attorney before your appointment.

Your Fingerprints Couldn’t Be Read

You may get a second notice. Go to it. This is common and it doesn’t mean anything is wrong with your case.

Separate Notices for Each Family Member

Each person goes with their own notice and ID. If the appointments are on different days, each person attends their own.

You Need to Travel Outside the U.S.

Be very careful. If you leave the U.S. while your I-485 is pending without approved travel permission (advance parole), USCIS may treat your green card application as abandoned. Talk to your attorney before you book any trip.
