The process of applying for a green card from within the United States, as opposed to applying from outside the United States using consular processing. It is called “adjustment of status” because the applicant changes from one status (their original visa) to another (permanent U.S. residence). See our green card adjustment of status guide for more information.


Eligibility to enter the United States. If a person is found to be admissible, they will be allowed to enter the country after being inspected by an immigration officer. See also inadmissibility.


The date that a person’s immigration status in the United States will expire, as marked in their I-94 travel record. See also duration of status (D/S).


Permission to reenter the United States after traveling abroad without applying for a new visa. Green card applicants can use Form I-131 to apply for advance parole in order to travel abroad without abandoning their application. See also green card.


A sworn statement submitted in writing, often witnessed by a notary. See also Affidavit of Support.


A document in which a person promises to support an immigrant financially, and to reimburse the U.S. government for the cost of any public assistance they receive. Usually submitted as part of a green card application. Read more here.

Under U.S. tax law, green card holders and people who spend significant amounts of time in the United States are considered “resident aliens,” while other foreign nationals, such as temporary visa holders who haven’t yet been in the United States long enough to qualify as “resident,” are considered “nonresident aliens.” See also foreign national.


A number assigned by U.S. Citizenship and Immigration Services (USCIS) to each person who files a visa or immigration application. The A-number — also sometimes called a “USCIS number” or “USCIS#” — remains the same for a person’s whole life, even if they file several different visa or immigration requests. See also case number.


A request to an outside authority to overturn an official decision or ruling. Some immigration decisions can be appealed to the USCIS Administrative Appeals Office (AAO) or the Board of Immigration Appeals (BIA), an office within the Department of Justice. Other decisions can’t be formally appealed, but can be referred back to the issuing office for reconsideration. See motion to reopen or reconsider.


Protection and immigration benefits granted to a person already in the United States, or at a U.S. port of entry, because they fear persecution in their home country.

A nonimmigrant visa issued for temporary travel to the United States. The B-visa includes the B-1 visa (used for business) and the B-2 visa (used for tourism and pleasure). Since many people combine business and pleasure during trips to the United States, the visa is often issued as a single multipurpose B-1/B-2 visa.



A number issued by USCIS to keep track of individual immigration and visa applications. A single person can have multiple different case numbers (also known as “receipt numbers”) tracking their different immigration requests and visa applications. See also alien registration number.

Learn more about the CR-1 Visa.


A period of time that a green card holder spends in the United States after gaining U.S. residence. Permanent residents must spend between 3 and 5 years continuously resident in the United States in order to qualify for U.S. citizenship.

Something that springs from (or “derives from”) another source. In the context of immigration, a person is considered “derivative” if their immigration status depends on the status of their spouse or parent. For example, the child of a green card holder is often eligible for a green card of their own. The person receiving a benefit in this way is called a “derivative beneficiary,” and the visa or other benefit they receive is sometimes called a “derivative benefit” or “derivative classification.”


The ability to make decisions using one’s own judgement. In some situations, immigration officials are required to make specific rulings; in others, they have broad powers to use their own judgement to decide whether to approve or deny an immigration benefit.


For immigration and tax purposes, your domicile typically refers not just to your house or apartment, but to your country of residence. This is often referred to as your “country of domicile” or being “domiciled in” a specific country. When applying for a marriage green card, a sponsoring spouse who lives outside the United States needs to provide proof of significant ties to the U.S.


A term that refers to a person’s intentions in coming to the United States. To have dual intent is to use a temporary or nonimmigrant visa while simultaneously planning to immigrate permanently to the United States. Most temporary visas don’t allow dual intent, and applying for a green card while using such a visa can cause serious problems. A few visas, such as the H-1B and L-1 visas, do allow for dual intent, allowing them to be used as a stepping stone to a green card.


An exact copy, or to make an exact copy. In the immigration context, many forms and documents must be submitted in duplicate form (in other words, a photocopy instead of the original). Learn how to produce flawless document copies for immigration applications.


A mark or stamp made on a temporary visitor’s I-94 record (in the admit-until date section) when they are admitted to the United States. The D/S mark (sometimes also referred to as “Duration of Stay”) allows a visitor to remain in the United States for as long as they maintain their current immigration status. A student visa holder can often remain in the United States until they complete their educational program, but loses their status once they are no longer enrolled in classes, for instance.

A diplomatic office, usually located in a foreign country’s capital city and headed by an ambassador. In many countries, the United States also maintains smaller diplomatic offices called consulates in important towns and cities. Both consulates and embassies offer a wide range of immigration services.


To leave one’s home country in order to live permanently in a new country. Sometimes confused with immigrate, which means to move permanently to a new country. You emigrate from one place in order to immigrate to somewhere else.


The right to work in the United States. Green card holders automatically have employment authorization, but many other non-citizens must request a work permit called an Employment Authorization Document (EAD). Employment authorization can be restricted to a specified employer, or can allow a person to work for any employer during their time in the United States.


A green card obtained in one of several employment-based (EB) categories. Employer-sponsored green cards, investor green cards, and green cards for immigrants with exceptional skills and abilities are all considered employment green cards. See also family preference and immediate relative.


To rapidly accelerate or increase the priority level of a given issue. In the immigration context, issues may be escalated when they need special attention. These issues may be moved ahead in line for faster processing or review by an immigration officer or manager.


To keep out or not include. In the immigration context, “exclusion” typically refers to a foreign national being denied entry into the United States through a removal procedure.


To speed up the progress of something; “expeditious” means speedy or quick. Under immigration law, certain cases can be expedited, meaning that a decision is reached more quickly than the normal processing time.


To become invalid. Most visas carry an “expiration date” that shows the latest date by which the visas can be used to request entry into the United States. Note that it is possible to have an expired visa without losing one’s immigration status. Your visa’s expiration date is the last date that you can use the visa to travel to the United States, but once admitted to the United States you will receive a D/S mark or admit-until date that tells you how long you are allowed to remain in the country.



Foreign nationals who are eligible for green cards because they are related to a U.S. citizen or permanent resident, but who are not the immediate relative (spouse, unmarried minor child, or parent) of a U.S. citizen. Adult or married children of U.S. citizens and green card holders, spouses and unmarried minor children of green card holders, and siblings of adult U.S. citizens are all considered family preference immigrants.

In the context of immigration, gender typically refers to one’s sex at birth. Transgender immigrants can ask USCIS to change the gender indicated on their official immigration documents, including green cards, by presenting court documents, a letter from a healthcare provider, or a government-issued document (such as a passport or driving license) confirming their requested gender designation.

The I-797 can be used to notify you that a requested immigration benefit has been approved or denied, to confirm receipt of payment, to schedule or reschedule appointments and interviews, or to request additional evidence in connection with an application.


Sometimes called the I-94 travel record, this document tracks the arrivals and departures of visitors to the United States, and can be used to prove lawful entry and current status. You may be issued a paper I-94 when you enter the United States, but in most cases I-94 records are now managed digitally. You can check your online I-94 record and travel history on the CBP website.


For the purposes of green card sponsorship, immediate relatives are defined as spouses of U.S. citizens, children (aged under 21 years old and unmarried) of U.S. citizens, and parents of U.S. citizens (if the U.S. citizen is at least 21 years old). See also family preference.

The legal category in which someone has been admitted into the United States. While someone is maintaining their immigration status in the United States, they are subject to various rules, responsibilities, and benefits associated with that particular status. Someone on a student visa might have to be properly enrolled in classes at their university in order to maintain their status, for instance. Note that your immigration status and your visa are different things; your visa is the specific document (such as an F-1 student visa) that you use to travel to the United States, while your status is the category under which you are admitted and allowed to remain in the country (such as being in F-1 status as a student enrolled in a qualifying degree program). There is no such thing as “visa status” under U.S. immigration law.


The quality of not being admissible. For immigration purposes, someone found inadmissible is barred from or ineligible for entrance to the United States, or from receiving a visa, often because of their conduct or circumstances.


The U.S. government agency that collects taxes from individuals and businesses. Records of a person’s payments to the IRS often form an important part of the supporting documents used in subsequent immigration applications.


A face-to-face meeting for the purposes of obtaining information. Many visas and other immigration benefits, including green cards and naturalization, require that the applicant attend an interview.

For example, the U.S. federal court system has jurisdiction over most immigration cases within the United States.



A fiancé(e) visa that allows a foreign national to travel to the United States for the purpose of marriage to a U.S. citizen.

The fiancé(e)’s dependents can be issued K-2 visas providing equivalent benefits. Read more here.


A visa allowing the spouse of a U.S. citizen to travel to the United States and adjust their status from within the country. The K-3 is seldom used since in most cases it is easier and faster to apply for a green card through consular processing. Read more here.

A period of employment permitted to the holders of F-1 student visas during or after their studies. Students who complete STEM degrees can extend their OPT period, making the program a valuable pathway to employment in the United States while users apply for H-1B visas, green cards, or other more permanent solutions.


To overstay means to remain in the United States beyond the admit-until date listed on one’s I-94 travel record, and thus to fall out of status. (This might not be the same thing as remaining beyond the expiration date on one’s visa.) Overstaying can cause serious problems for future visa applications, and even lead to the visa-holder being barred from returning to the United States for up to 10 years. See also Duration of Status.

Any border crossing, seaport, or airport where people enter the United States. USCIS field offices and service centers are also considered ports of entry because people can receive immigrant status there.


The income level below which a person or household is considered to live in poverty. The guidelines, which are set by the U.S. government, vary based on household size and are higher for people resident in Hawaii or Alaska. For the purposes of immigration, poverty guidelines are used to determine whether applicants qualify for fee waivers, and also to set minimum income levels for certain immigration benefits. See also public charge rule.


The date that USCIS received your I-130 petition. It represents your place in the line of people waiting for green cards to become available, as shown in the monthly visa bulletin. You can find your priority date on the I-797 form USCIS sent when your I-130 petition was approved. See also final action date and date for filing.

Also referred to as a “Permit to Re-Enter” or “white passport,” this passport-like document can be used by green card holders to travel abroad for more than 1 year but less than 2 years without being presumed to have abandoned their U.S. residence. A green card holder can request a reentry permit before leaving the United States in order to document their intention to return and to remain a U.S. resident. A permit can also be used instead of a passport by green card holders who are unable to gain a passport from their country of citizenship.

Any non-U.S. citizen who resides in the United States. The term includes green card holders, but for tax purposes many other non-citizens are considered resident aliens. See also nonresident alien.


To go back to a previous state. In the context of immigration, “retrogression” is when somebody’s place in line for a green card moves backward instead of forward, leaving the applicant with a longer wait. This can occur when demand for visas outpaces the government’s ability to process applications, or when only a limited number of visas are issued in a given category each year.


A green card holder who has traveled abroad and who is now returning to the United States. If they have been abroad for more than 1 year, the green card holder will need a returning resident visa.


A visa issued to green card holders who have been abroad for more than 2 years, or for more than 1 year without first requesting a reentry permit. Applicants must be able to show their extended absence was due to reasons beyond their control, and that they did not intend to abandon their U.S. residence.


A notice issued by USCIS asking an applicant to provide additional information or evidence in support of their application. Nobody wants to receive an RFE, but it doesn’t mean your application is more likely to be denied, as long as you respond carefully and promptly. Read more here.


To cancel, reverse, or take something back. In the context of immigration, for example, the government can revoke a visa if the visa holder is no longer eligible.

A condition, or a state of being. For immigration purposes, “status” can refer to the condition or progress of a specific immigration case, such as whether an application has been received or adjudicated. It can also refer to a person’s immigration status. Note that there is technically no such thing as “visa status”; your visa is a document that allows you to travel to the United States and request admittance, after which you gain an immigration status based on your reason for traveling and the laws and regulations that cover your visit.


An acronym for Science, Technology, Engineering, and Mathematics. Some student visa holders who complete degrees in STEM subjects are eligible to remain and work in the United States for longer than students in other disciplines. See also Optional Practical Training.
