ASC Appointment Notice Code 1, 2, 3 or 5: What USCIS Is Actually Collecting

The single digit printed on your I-797C biometrics notice tells you which biometrics the ASC will take — ten prints, four prints, or just a photo and signature. Here is the full legend.

You are holding a Form I-797C, Notice of Action, with your Application Support Center appointment on it, and somewhere in the header block — next to the case type, the notice date and your receipt number — there is a small field with a single digit in it. Code 3. Or CODE: 1. The notice does not say what it means. Neither does the USCIS page on preparing for your biometric services appointment, which tells you what to bring and nothing about the number.

Here is the legend practitioners use, followed immediately by the honest caveat that goes with it.

The ASC notice code legend

⚠️ Read this before you use the table above. USCIS does not publish this mapping. There is no agency document that assigns meanings to notice codes 1, 2, 3 and 5. This legend is the working convention used by immigration attorneys and corroborated by consistent applicant reports of what actually happens at the workstation — not an agency rule. It can change without notice, and an individual ASC may capture more than the code suggests, because 8 CFR 103.16 gives DHS broad authority to collect and store biometric information from any benefit requestor. The Code 5 row is the thinnest-sourced line in the table: the four-finger description comes from attorney commentary and applicant reports, and we could not confirm it against any USCIS source. Treat it as reported, not confirmed.

How thin is the official record? The USCIS Policy Manual has a section titled "Biometrics Collected" at Volume 1, Part C, Chapter 2. Its subsection on Fingerprints reads [Reserved]. Its subsection on Signatures reads [Reserved]. USCIS has not published guidance on the mechanics of what it takes and when. That is the vacuum every code explainer on the internet, including this one, is filling.

For the full step-by-step of the appointment itself, our guide to what actually happens inside the ASC is the walkthrough. This page is only the decoder.

Where the code appears on Form I-797C

The code sits in the header block of the notice, in the same cluster of fields as the case type, notice date, receipt number and your USCIS account number. It is not in the body instructions, and it is not explained anywhere on the page.

Layouts differ. USCIS generates notices from more than one system, and the format varies by the form you filed — an I-539 dependent extension, an I-765 employment authorization application and an I-485 adjustment application do not all produce identical notices. Some notices carry no code field at all.

A missing code is not a defect and is not a reason to call USCIS or reschedule. If the date, time and address are printed and legible, the notice is doing its job. Appear as scheduled.

(If you are an F-2 or H-4 spouse who received a biometrics notice for a dependent filing, the I-539 extension and change of status guide covers where that appointment sits in the wider process.)

Why USCIS collects three different things

The legend stops feeling arbitrary once you see that two completely independent jobs are being done at one appointment.

Identity and background. Fingerprints go to the FBI for a criminal history check. USCIS describes the purpose plainly: the biometrics you provide allow the agency to confirm your identity and run required background and security checks. This is the security-vetting half, and it is why a ten-print roll exists at all.

Document production. A digital photograph and an electronic signature are what get physically printed onto a secure card. USCIS embeds a photograph when creating certain secure documents as a security feature. If you are waiting on an EAD, this half of the appointment is literally the manufacturing step for the card described in our Form I-765 OPT EAD filing walkthrough.

Codes 1 and 2 are each one half. Code 3 is both. That is the whole architecture.

One detail worth knowing before you go in: when you provide your electronic signature at the workstation, you are signing an attestation — USCIS calls it the "Acknowledgement of Appointment at USCIS Application Support Center" — that the information in your application and all supporting documents is complete and accurate, under penalty of perjury. It is not a formality. Read it.

What the code tells you about your case, and what it does not

This is the section this page exists for.

Why people think Code 2 means approval

The inference is not crazy. Code 2 captures exactly the three elements USCIS needs to print a card and nothing else — no ten-print roll, because the background check is presumably already done or not required. If the agency is collecting only the card-production inputs, it is reasonable to guess that a card is queued.

That reasoning gets repeated on forums as fact, and it arrives at a conclusion the premise does not support.

Why it is not an approval notice

USCIS does not communicate adjudicative decisions through ASC workflow fields. Biometrics can be collected and the case can still receive a Request for Evidence, still be denied, or have card production halted. A code is an instruction to a workstation about what to capture. It is not a notice, it is not a decision, and it carries no legal effect.

The authoritative signals about your case are the case status record in your USCIS online account and the written notices USCIS mails you. Nothing else. If you want to read your case correctly, start with how to read your receipt notice and track case status, which explains what the status strings actually mean and which ones matter.

And if you have been treating a Code 2 as good news because your EAD is overdue, the honest next step is the action plan for a delayed OPT EAD card rather than another week of waiting.

What it genuinely does tell you

It tells you what will physically happen to you in the room. That is a small thing, but it is not nothing. If you have a hand injury, a skin condition, occupational wear on your fingertips, or scarring, knowing whether you are facing a full ten-print roll or a photo-and-signature capture is useful preparation — and it tells you whether the fingerprint-waiver question below is likely to come up at all.

What to bring, whatever the code says

USCIS asks for two things:

1. Your biometric services appointment notice — the paper I-797C. Bring every notice if you received more than one.
2. Valid, unexpired photo identification. USCIS names a Permanent Resident Card (Form I-551), a passport, or a driver's license as examples.

No version of the code changes this list. None of them requires you to bring your underlying petition or your supporting evidence. None of them changes the roughly 15 to 30 minutes you will spend at the workstation — your total door-to-door time is driven by the center's queue that morning, not by the digit on your notice. You may also bring someone with you, including a family member, attorney or accredited representative.

Special cases the code does not cover

Biometrics reuse. USCIS may reuse a previously collected photograph rather than making you appear again, and in December 2025 the agency tightened the window sharply. Under Policy Alert PA-2025-29, issued December 12, 2025 and effective for benefit requests filed on or after that date, USCIS may only reuse a photograph if no more than 36 months have passed since it was collected at a biometric services appointment. Reuse is not permitted at all for Form N-400, Form N-600, Form I-90 or Form I-485, which require new biometrics including a new photograph. This replaced a prior standard that allowed a photo to be up to 10 years old on an agency-issued document. Reuse is USCIS's decision, not something you can request.

Fingerprint waivers. Where prints genuinely cannot be captured because of a medical condition — disability, birth defects, physical deformities, skin conditions, psychiatric conditions — USCIS can waive the fingerprint requirement rather than stall the case. This is not something you elect. You must appear in person, an officer or technician must attempt the capture, and the officer must determine that you cannot be fingerprinted at all or cannot provide a single legible print. A waiver is valid only for the filings listed on that ASC notice, and USCIS's decision to deny a waiver is final and cannot be appealed.

Mobile and remote collection. USCIS operates mobile biometrics collection in limited circumstances as an accommodation, and it will tell you if it can provide the service. These appointments are not scheduled through the standard ASC notice. Note also that USCIS does not collect biometrics from people in custody at correctional institutions and does not grant reschedule requests on the ground of detention or incarceration.

You pay nothing at the ASC — and the old $85 biometrics fee is gone. Under the fee rule effective April 1, 2024, USCIS folded biometric services costs into the underlying form fee for most filings. Checking the current Form G-1055 fee schedule (edition 05/29/26), a separate $30 biometric services fee survives only for Form I-821 Temporary Protected Status filings and for certain forms accepted on behalf of the Executive Office for Immigration Review. There is no separate biometrics fee on an I-765, an I-539 or an I-485. If an older guide or a preparer quotes you $85 as a line item, that figure is stale — our 2026 USCIS fee schedule breakdown has the current numbers.

If you cannot make the appointment

USCIS now accepts rescheduling through a myUSCIS online account for most biometrics appointments, in addition to the USCIS Contact Center at 800-375-5283 (TTY 800-767-1833). It does not accept requests by mail or in person at a USCIS office. The online tool has hard limits: you cannot use it for an appointment that has already been rescheduled two or more times, one that is within 12 hours of the scheduled time, or one that has already passed. For those, call.

Making the request before the scheduled time is the entire ballgame. Under 8 CFR 103.2(b)(13)(ii), a benefit request is considered abandoned and denied if you fail to appear, unless by the appointment time USCIS has received a change of address or a rescheduling request it concludes warrants excusing the failure. You also have to show good cause. USCIS's published examples include illness or a medical appointment, previously planned travel, a significant life event such as a wedding, funeral or graduation, an inability to obtain transportation, an inability to get leave from work or caregiver responsibilities, and a notice that arrived late or never arrived at all.

If the appointment has already passed, stop reading general guides and act. A denial for abandonment cannot be appealed, and a motion to reopen under 8 CFR 103.5(a)(1)(i) must generally be filed within 30 days of the decision. Our guide to what happens if you miss the appointment entirely covers the recovery path, and a missed appointment with a case already in denial is an immigration attorney's question, not an article's.

This page decodes a notice field. It stops there. If your question is whether a code change between notices means USCIS reopened your background check, whether a prior arrest will surface on an FBI check, or whether you should travel before your appointment, those turn on your individual record and the specific filing that is pending. F-1 and F-2 readers should raise anything touching status maintenance with their DSO first. Anything involving criminal history, a prior immigration violation, or an appointment you have already missed goes to an immigration attorney, and for the missed appointment, immediately.

Frequently asked questions

What does Code 1 mean on a USCIS biometrics appointment notice?

Code 1 is the ten-print code. The Application Support Center will roll and scan all ten of your fingerprints so USCIS can run an FBI criminal history check. Code 1 appointments do not normally include a photograph or signature capture, because USCIS already has an acceptable photo and signature on file or does not need one to produce a card.

What does Code 2 mean on a USCIS biometrics appointment notice?

Code 2 is the document-production code. The ASC takes a digital photograph, an electronic signature, and a limited fingerprint capture — commonly the index fingers only. These are the three elements USCIS needs to physically print a secure card such as an EAD or a green card. Code 2 is not an official notification that your case has been approved, and USCIS does not publish it as one.

What does Code 3 mean on a USCIS biometrics appointment notice?

Code 3 is the combined code and the one most applicants see. It means the ASC will capture all ten fingerprints for the FBI background check plus your photograph and signature for card production. Practically, a Code 3 appointment runs the same length as any other — roughly 15 to 30 minutes at the workstation.

What does Code 5 mean on a USCIS biometrics appointment notice?

Code 5 is reported to be a reduced-fingerprint variant — a four-finger slap capture from one hand, plus photograph and signature — rather than the full ten-print roll. It appears on notices less often than Codes 1, 2 and 3. Because USCIS does not publish a public legend for these codes, treat any Code 5 description you read online, including this one, as a working convention rather than an agency rule.

Does USCIS officially publish what the biometrics notice codes mean?

No. USCIS has general statutory and regulatory authority to collect fingerprints, photographs and signatures, and it describes those categories in the Policy Manual, but it does not publish a public key that maps notice codes 1, 2, 3 and 5 to specific capture types. The legend circulating online comes from immigration attorneys and ASC staff. If the code on your notice matters to a decision you are making, call the USCIS Contact Center rather than relying on a forum.

Does the code on my notice change what I need to bring to the ASC?

No. Regardless of the code, bring the original paper I-797C appointment notice and a valid government-issued photo ID. The code tells the ASC workstation what to capture; it does not change your document checklist and it does not change how long the appointment takes.

My appointment notice has no code printed on it. Is something wrong?

Not necessarily. Notice formats vary by form type and by the USCIS system that generated them, and some notices simply do not print a code field. A missing code is not a defect in your notice and is not a reason to reschedule. Appear at the date, time and location printed on the notice.

A notice code tells you what happens in the room. It does not tell you where your case stands, and no article can — that comes from your USCIS account and the notices you receive.
