A USCIS notice rarely explains itself. It uses a term and assumes you know what follows. Get an interpretation wrong, and you can miss a filing window without realizing it until it’s too late.
This glossary was made so you understand what these terms mean when you encounter them on a notice, in a decision, or on an old form. Some entries cover documents like Form I-197, which USCIS stopped issuing over 40 years ago but still counts as valid proof of citizenship today. Others, like the rules around a Request for Initial Evidence, changed as recently as August 2026.
These are the terms that describe where you are in the immigration process.
The Visa Bulletin is a monthly update published by the U.S. Department of State showing when certain employment-based and family-based green card applicants can move forward. It is organized by preference category and country of chargeability. The bulletin uses priority dates to show which cases are currently eligible for filing or final approval, depending on the chart USCIS instructs applicants to use for that month.
Priority date determines a place in line for an immigrant visa or green card. For many employment-based cases, it is tied to when the petition or labor certification was filed. See how to check priority date here.
Each month, the Department of State publishes the Visa Bulletin, which sets cutoff dates by preference category and country of chargeability. Your priority date must be earlier than the applicable cutoff date before you can move to the next stage of the green card process.
The Dates for Filing chart shows when a green card applicant may be allowed to submit Form I-485, even if a visa number is not yet available for final approval. A priority date must be earlier than the date listed for the applicant’s category and country. USCIS decides each month whether this chart can be used for adjustment-of-status filings.
Final Action Dates chart shows when an immigrant visa number is available for a green card case to be approved. If an applicant’s priority date is earlier than the listed cutoff date, the case is considered current for final action. USCIS or a U.S. consulate can approve the application once all other eligibility requirements have been satisfied and a visa number remains available.
Adjustment of Status (AOS) is the process of applying for a green card while you are physically present in the United States. You file Form I-485, and if USCIS approves it, you become a lawful permanent resident without leaving the country. Your priority date must be current under the current month’s Visa Bulletin to file Form I-485. Check out the complete 2026 guide to filing Form I-485.
Consular processing is used when your case is processed through the National Visa Center (NVC) before being transferred to a U.S. embassy or consulate for your immigrant visa interview.
Visa availability can also change from month to month. A date that is current today may move backward later, a shift known as “retrogression”. While this does not cancel an approved petition, it can delay when a case can move forward. Our priority date retrogression guide explains what that means for a pending case.
A conditional permanent resident has lawful permanent resident status, but the green card is valid for only 2 years instead of the usual 10. This status is commonly given in marriage-based cases when permanent residence is approved before the couple has been married for two years.
The word “conditional” does not mean the person has fewer day-to-day rights. A conditional resident can live and work in the United States like any other permanent resident. The difference is that the status must be reviewed again before the two-year period ends.
To remove the conditions and receive a standard ten-year green card, Form I-751 is filed during the 90 days before the conditional card expires. USCIS uses the filing to confirm that the qualifying marriage was genuine and not entered into only for immigration purposes.
Almost everyone assumes "citizen" and "national" mean the same thing. Under INA 101(a)(22), they are not.
They do not hold full citizenship rights such as voting in federal elections. It is a narrow category, yet it explains why some official forms distinguish "citizen" from "national" instead of using the terms interchangeably.
These terms come up most during the USCIS adjudication process, especially when an officer reviews a petition or asks for additional information. Here is what each one means:
A Request for Evidence (RFE) is a notice from USCIS asking for more documentation or clarification before it can decide your case. It simply means the officer reviewing your file found an issue that additional evidence can solve. RFEs are common across O-1, EB-1A, and EB-2 NIW filings, and a well-prepared response can still lead to approval. What is important is answering every point the notice raises, not just the ones that feel easiest to address.
A Request for Initial Evidence (RFIE), is a narrower notice. It means basic information was missing from your original filing. This includes a required signature, a missing form, or an unpaid fee. USCIS is telling you the case cannot even begin proper review without that piece in place.
Under a USCIS Policy Alert issued August 5, 2026, officers may deny an O-1A, EB-1A, or EB-2 NIW petition outright. They do not have to issue an RFE or NOID first if required initial evidence is missing or the filing does not establish eligibility at the time of submission. Check out the full breakdown of the August 2026 update.
A Notice of Intent to Deny (NOID) is more serious than either RFE type, as it shows USCIS has reviewed a case and currently plans to deny it. Before issuing a final decision, however, USCIS gives the applicant a limited period, often 30 days, to respond with evidence or arguments addressing those concerns.
NOIDs are not a denial. It is the last opportunity to respond before one is issued. Treat it with the seriousness of an appeal.
Form I-797C, Notice of Action, is one of the main ways USCIS communicates updates about a case. It may confirm that a filing was received, rejected, transferred, reopened, or scheduled for an appointment.
The notice does not grant immigration status or a benefit by itself. Its most practical feature is often the receipt number, which can be used to track the case online and reference the filing in future communication with USCIS.
Every I-797C should be read carefully. A receipt notice, rejection notice, transfer notice, and appointment notice can look similar at first glance, but each carries a very different instruction or consequence.
These terms show up more in the reasoning behind a decision. Two things separate them from the notice-and-evidence terms above:
Nunc pro tunc is Latin for "now for then." In immigration law, it refers to USCIS's discretionary power to treat a late or defective filing as if it had happened on time. It shows up most in requests to backdate an approval after a missed deadline caused by circumstances outside the applicant's control.
USCIS has cited things like government shutdowns as the kind of extraordinary circumstance that can support a nunc pro tunc request. Approval is not guaranteed.
A prima facie case is established when enough initial evidence has been submitted to support eligibility for an immigration benefit without requiring further inquiry at that stage. In simple terms, the filing has met the basic evidentiary threshold needed to move forward.
In some cases, including certain VAWA self-petitions, a prima facie determination may also provide access to temporary benefits while USCIS continues reviewing the full case.
However, a prima facie finding is not an approval. USCIS still reviews the complete record before making a final decision, and the initial finding does not guarantee that the petition will ultimately be approved.
Discretionary relief refers to immigration benefits that are not granted automatically once the basic eligibility requirements are met. Qualifying for the benefit allows the case to be considered, but USCIS may still weigh the broader facts and circumstances before deciding if approval is warranted.
The officer can consider both favorable and unfavorable factors in the record. As a result, meeting every listed requirement does not necessarily guarantee that the benefit will be granted.
USCIS stopped issuing these documents decades ago. However, "discontinued" does not mean "invalid."
Form I-197 was issued to naturalized US citizens living near the Mexican or Canadian border, mainly to make frequent border crossings easier. USCIS stopped issuing it on April 7, 1983.
Under 8 CFR 235.10, any I-197 issued before that date remains valid documentation of US citizenship today. There is no process to replace one if it is lost, since USCIS no longer produces the card.
“Certificate of Application” is not the name of a current USCIS immigration document. The term is sometimes confused with Form N-600, Application for Certificate of Citizenship, which is used to request official proof of U.S. citizenship acquired at birth abroad or derived after birth. Form N-600 is the application itself. Once USCIS approves it, a Certificate of Citizenship is issued as evidence of U.S. citizenship.
The Form I-151 was the original green card, issued to lawful permanent residents starting in the 1940s. USCIS replaced it with Form I-551, the Permanent Resident Card still in use today. Old I-151 cards continued to be accepted for years after that transition before being fully phased out.
Immigration cases involve several numbers, codes, and document references, each serving a different purpose. Knowing what each one identifies, where to find it, and whether it expires can help prevent avoidable filing and tracking errors.
Form I-693 records the immigration medical examination required for most green card applicants. The exam must be completed by a USCIS-designated civil surgeon and is used to determine any health-related grounds of inadmissibility apply, including vaccination requirements and screening for certain communicable diseases.
The validity of Form I-693 depends on when the civil surgeon signed it.
For forms signed before November 1, 2023, the medical exam remains valid for two years from the date of the civil surgeon’s signature.
For forms signed on or after November 1, 2023, validity is tied to the Form I-485 with which the medical exam was submitted. The I-693 remains valid while that adjustment-of-status application is pending.
If the I-485 is withdrawn or denied and a new application is later filed, a new medical examination is generally required. Check out our guide on I-485 requirements.
Every accepted USCIS filing gets a 13-character receipt number, printed on your Form I-797C. It identifies a case and is what you enter into the USCIS online case status tool to check where the filing stands. Losing it does not end your case, but it makes tracking progress harder than it needs to be.
Immigration deadlines can determine whether a filing remains valid, a response is accepted, or lawful status can be maintained. The terms below explain some of the most important timing rules, including grace periods and USCIS response deadlines.
“Error window” is not an official USCIS term. In most searches, the phrase refers to the discretionary grace period available to certain nonimmigrant workers after their employment ends.
The rule can provide up to 60 consecutive calendar days to workers in E-1, E-2, E-3, H-1B, H-1B1, L-1, O-1, and TN status, as well as qualifying dependents. The period ends earlier if the person’s authorized stay expires before the 60 days are complete.
During this time, a worker may be able to secure new qualifying employment, apply for a change of status, or prepare to leave the United States. The grace period is discretionary rather than automatic and is generally available once during each authorized validity period.
USCIS sets the response deadline for a Request for Evidence directly in the notice. The amount of time provided varies by case and by the type of evidence requested, but an RFE response period cannot exceed 12 weeks.
A Notice of Intent to Deny has a shorter deadline because USCIS has already identified grounds that could lead to denial. The maximum response period for a NOID is 30 days.
The date printed on the notice should always be controlled. Missing the stated deadline can leave USCIS to decide the case based on the existing record or, in some circumstances, treat the filing as abandoned.
Immigration terms have consequences that are easy to miss from the wording alone. A notice may set a deadline, request specific evidence, affect case status, or require action within a limited window.
The goal is not to memorize immigration terminology, but to understand what a term means in the context of the case and what needs to happen next.

Nunc pro tunc is Latin for "now for then." It refers to USCIS's discretionary power to treat a late or defective filing as if it had happened on time, usually to fix a gap caused by circumstances outside the applicant's control. Approval is never automatic and depends on the strength of the evidence supporting the request.
No. The nunc pro tunc meaning is narrower than an appeal. An appeal challenges a decision USCIS already made. A nunc pro tunc request asks USCIS to backdate an approval to correct a timing problem, not to reverse a substantive finding.
A Request for Initial Evidence, or RFIE, means something basic was missing from your original filing, such as a signature, a required form, or a fee. Since August 2026, missing initial evidence on an O-1A, EB-1A, or EB-2 NIW petition can lead straight to a denial rather than an RFIE, so treating your initial filing as complete matters more than it used to.
Form I-197 is an old immigration form: a U.S. Citizen Identification Card issued to naturalized citizens near the Mexican and Canadian borders. USCIS stopped issuing this form in 1983, but any card issued before that date remains valid documentation of citizenship today.
This is not a real USCIS document. If you searched for a certificate of application, you were likely thinking of Form N-600, the Application for Certificate of Citizenship, which is the form people file to obtain an actual Certificate of Citizenship.
Form I-693 is the medical exam record required for most green card applications. Search terms like "i 693 form uscis" usually come from applicants trying to confirm whether their exam is still valid, which now depends on the civil surgeon's signature date rather than a fixed expiration.
A conditional green card is a two-year version of a standard green card, issued when a marriage-based petition is approved less than two years after the wedding. It must be converted to a standard ten-year card by filing Form I-751 during the 90-day window before it expires.
AOS stands for adjustment of status, the process of applying for a green card while remaining inside the United States. It requires physical presence in the US and a current priority date under the Visa Bulletin.
An RFE asks for more evidence because your case is missing something that additional documentation can fix. A NOID means USCIS has already concluded, based on the record so far, that it plans to deny your case, and gives you a shorter, final window, commonly 30 days, to change that outcome. Form I-797C is the notice type most often used to deliver an RFE update, though it does not itself grant any status.
Not quite. Every US citizen is a national, but the reverse is not true. A small group of non-citizen nationals, mostly people born in American Samoa or Swains Island, hold US nationality without full citizenship. This is the main source of confusion around the citizen and non-citizen distinction in immigration terminology.
