What to Expect at Your ASC Appointment for Biometrics

What happens at an ASC appointment

An ASC appointment is where USCIS collects your fingerprints, photograph, and signature for immigration cases. ASC stands for Application Support Center. You will go to a physical location, have your biometrics taken by staff, and leave with a receipt. The whole process usually takes 15 to 30 minutes, though wait times vary by location and time of day.

USCIS uses these biometrics to run background checks, verify your identity, and process your case. You cannot skip this step if USCIS has scheduled you for it — it is a required part of most immigration applications and petitions.

Key Takeaways

• Your appointment notice will tell you the exact ASC location, date, and time — arrive 10 to 15 minutes early with the notice and a valid ID.
• Bring original documents that match the name on your notice; if your name has changed, bring proof of the change (marriage certificate, court order, or naturalization certificate).
• Wear clean, plain clothing with no heavy makeup or accessories that might interfere with your photograph.
• If you cannot make your scheduled appointment, contact USCIS before the date to reschedule; missing it without notice may delay your case.

Documents to bring to your ASC appointment

Bring your appointment notice — the letter USCIS mailed you with the date, time, and location. Bring a valid government-issued photo ID that matches the name on your notice. A passport, driver's license, or state ID card all work. If you do not have a photo ID, call the ASC location listed on your notice to ask what alternatives they accept.

If your name on the notice does not match your current legal name, bring proof of the change. This means an original or certified copy of a marriage certificate, divorce decree, court order for a name change, or naturalization certificate. A photocopy is not enough — bring the original or a certified copy.

Do not bring children unless they also have scheduled appointments. Do not bring weapons, sharp objects, or items that will set off a metal detector. ASC locations have security screening, and prohibited items will delay you or prevent entry.

What to wear and how to prepare

Wear clean, plain clothing. Your photograph will be part of your immigration record, so avoid heavy makeup, sunglasses, or large hats. If you wear glasses for vision correction, you may wear them for the photograph, but not sunglasses. Remove any head coverings unless you have a religious reason to wear one — in that case, the covering must allow your face to be clearly visible.

Arrive 10 to 15 minutes before your scheduled time. ASC locations often run on time, and arriving late may mean you lose your slot. If you are running more than 15 minutes late, call the location to let them know.

If you have a medical condition that affects how you can sit, stand, or position your hands for fingerprinting, mention it when you arrive. Staff can sometimes adjust the process, but they need to know in advance.

What happens during the appointment

When you arrive, check in at the front desk with your notice and ID. A staff member will call you when it is your turn. They will verify your identity, take a digital photograph of your face, collect your signature, and scan your fingerprints using an electronic scanner. You will place each finger on the scanner one at a time — the process is quick and painless.

The staff member may ask you to confirm your name, date of birth, and address. If any information is wrong, tell them immediately so they can correct it in the system. Do not sign anything or leave until you have reviewed what they entered.

At the end, you will receive a receipt showing that your biometrics were collected. Keep this receipt until your case is decided. It proves you completed this step if there are any questions later.

After your appointment: what comes next

USCIS will process your biometrics and run background checks. This usually takes two to four weeks, though it can take longer depending on the type of case and current processing times. You do not need to do anything while you wait.

Once the background check is complete, USCIS will continue processing your case. You may receive a notice for an interview, a decision on your case, or a request for more documents. Check your USCIS account online or watch your mail for updates.

If you do not hear anything after six weeks, you can contact USCIS through their online account system or call their customer service line. Have your case number and appointment receipt ready.

If you cannot attend your scheduled appointment

Contact USCIS as soon as you know you cannot make it. Call the ASC location directly using the number on your notice, or go online to your USCIS account and request a reschedule. Do not simply skip the appointment — missing it without notice can delay your case or result in a denial.

USCIS will usually reschedule you for another date at the same location. If the location is too far away or you have a hardship, explain that when you reschedule. Some locations can accommodate requests to move to a closer ASC, but it depends on availability and your case type.

If you have a medical emergency or a death in the family, contact USCIS immediately and explain the situation. They may be able to work with you on timing.

Common issues at ASC appointments

If your fingerprints do not scan clearly, the staff member will try again or use a different method. This is normal and does not mean anything is wrong. Dry skin, calluses, or scars can sometimes make scanning harder, but staff are trained to handle this.

If your name on your notice does not match your ID, bring proof of the name change. If you do not have it with you, ask if you can reschedule to bring it. Do not try to proceed without matching documents — it will cause problems later in your case.

If you are not a U.S. citizen and do not have a photo ID, ask the ASC staff what documents they will accept. Some locations accept foreign passports, travel documents, or state ID cards even without a photo, depending on your case type.

Frequently Asked Questions

What if I lost my appointment notice?

Log into your USCIS account online to view your appointment details, or call USCIS customer service with your case number. They can tell you the date, time, and location. You do not need the physical notice to attend, but bring a valid photo ID and be ready to provide your case number at check-in.

Can someone go with me to my appointment?

Yes, you can bring a family member or friend for support, but they will not be allowed in the biometrics collection area. They can wait in the lobby. If you need an interpreter, contact the ASC location before your appointment to request one.

What if I am pregnant or have a disability that affects standing or fingerprinting?

Tell the staff member when you arrive. They can sometimes provide a chair, adjust the height of the equipment, or modify the process. Call the ASC location before your appointment if you want to discuss accommodations in advance.

Do I need to fast or prepare in any special way before my appointment?

No. Biometrics collection does not require fasting, medication changes, or special preparation. Just bring your documents, arrive on time, and wear clean clothing.

What if my biometrics expire before my case is decided?

USCIS will contact you if your biometrics need to be retaken. Biometrics are usually valid for 15 months, but this depends on your case type. If your case is still pending after that time, USCIS will schedule you for another appointment.
