The F-4 fourth preference family-based green card is for foreign persons who are brothers or sisters of a U.S. citizen. The U.S. citizen must be at least 21 years old to sponsor their biological siblings, paternal half-siblings (same biological father but different mother), step-siblings, or adopted siblings. The spouse and dependent children (unmarried and under 21 years old) of the U.S. citizen’s siblings can also qualify for a green card by being listed as a derivative person under the sibling’s F-4 family preference green card petition. 

Table of Contents

Under the F-4 family preference green card, a foreign person qualified as a sibling must (1) be the brother or sister of a U.S. citizen (i.e., share at least 1 common parent), and (2) the U.S. citizen must be at least 21 years old. The spouse and dependent children (unmarried and under 21 years old) of the U.S. citizen’s sibling can be qualified as a derivative person to obtain a green card along with the U.S. citizen’s sibling under the F-4 fourth preference family-based green card petition. 

The U.S. citizen and the foreign sibling must share at least one common parent. The sibling’s relationship with the U.S. citizen can be formed through biological parents, adoption, step-parent, or paternal half-siblings (same biological father but different mother). If the sibling is related through adoption, the adoption must have happened before the U.S. citizen or the sibling (adopted child) turned 16 years old. If the sibling is related through a step-parent, the parent’s marriage must have happened before the U.S. citizen or the sibling turned 18 years old.

The original statutory wording for qualified siblings in family-based green card petitions can be found in 8 CFR 204.2(g).

The F-4 family preference green card petitions (sibling of U.S. citizen) have four main requirements that need to be satisfied: evidence must be provided to the USCIS to show that (1) the sponsoring person must be a U.S. citizen who is at least 21 years old, (2) the family relationship between the foreign sibling and the U.S. citizen is qualified and real, (3) the foreign person will not become a public charge (typically the U.S. citizen must have income that is at least at the 125 % of the federal poverty level), and (4) the foreign person is admissible to enter the United States.

The total time an F-4 family preference green card takes is consisted of the processing time for (1) the F-4 family preference green card petition (Form I-130) with the USCIS and (2) the change of status when the person’s priority date becomes current by filing the Form I-485 application if adjusting status within the United States or the DS-260 application if doing consular processing at a U.S. consulate or embassy located outside the United States.  

Factors that influence the F-4 family preference green card processing time usually include but are not limited to where the person (or spouse) was born, if there was any Request for Evidence (“RFE”) issued, and the caseload of the USCIS service center, National Visa Center (NVC), and the U.S. consulate or embassy.    

A rough estimate for the F-4 family preference green card Form I-130 petition (sibling of U.S. citizen) can be around 21 to 172.5 months (i.e., 1 to 14 years) and premium processing is not available. Current estimates of the processing time can be checked here.  

Priority Date for Status Change

After the USCIS approves the F-4 family preference (siblings of U.S. citizen) green card petition (Form I-130), the person will then wait for their priority date to become current to apply for a change of status into a green card holder (lawful permanent resident). The priority date for the F-4 family preference (siblings of U.S. citizen) green card petition is the date that the USCIS receives the immigration petition (Form I-130).

There are two parts in the processing time for a change of status: (1) the time to when the person’s (i.e., U.S. citizen’s sibling’s) priority date becomes current which can range from no wait time to multiple years depending on what country the person was born in, and (2) the time to process Form I-485 for adjustment of status or DS-260 for consular processing which a rough estimate can range from 4 to 15 months. 

For F-4 family preference (siblings of U.S. citizen) green card petitions, the wait time for the person’s priority date to become current can roughly be around 15 years (with Mexico around 22 years). For people born in certain countries (based on country of birth and not country of citizenship) such as Mexico, India, or the Philippines, the wait time for their priority date to become current is usually longer than other countries under family preference green card petitions. 

The reason as to why there are different wait times for a priority date to become current is due to the total limit on how many green cards (i.e., immigrant visas) can be given out each year and a separate limit on how many green cards are allotted for each country. There are usually not enough available visas (i.e, amount of green cards that can be given out) for family preference green card petitions each year due to high-volume immigration so people would have to wait for their visas (green cards) to become available which would be based on when their priority date becomes current in the monthly Visa Bulletin released by the U.S. Department of State (DOS).

Cross-Chargeability

The cross-chargeability rule can be used in the F-4 family preference green card petitions by the siblings (brothers and sisters) of U.S. citizens and their spouse and unmarried minor children. Cross-chargeability is often used when the person’s country of birth has a visa backlog problem but the country of birth for the person’s spouse does not. The person born in the country that has a visa availability backlog problem will use the cross-chargeability rule to be charged against (use the quota of) the spouse’s country instead (this usually results in obtaining the green card much earlier). For example, a person born in China (which usually has a visa availability backlog problem) with a spouse born in South Korea (which does not have a visa availability backlog problem): both of them can use the quota of South Korea instead of China when they apply to change into their green card visa status. It does not matter which person is the primary person pursuing the green card petition. 

Minor children can be charged to either parent’s country of birth,  or in some circumstances the child can be charged to a third country that neither parent was born in or had residence in when the child was born. For example, both parents were born in Japan but their child was born in China during a temporary vacation there: the child can be charged against the quota of Japan. Under most circumstances, derivative beneficiaries (such as the spouse or children of green card visa applicants) cannot be eligible to apply to change into their green card visa status before the principal green card visa applicant. 

Please note that parents cannot use their minor children’s country of birth under the cross-chargeability rule. For example, both parents were born in China and their child was born in Japan. The parents cannot use Japan which is their child’s country of birth and would still need to use China which is their own country of birth to wait for their green card. 

Changing into the F4 family preference green card visa status (the lawful permanent resident immigrant visa status) is the final step in being able to work freely and live permanently in the United States. There are two ways to obtain the green card visa status: adjustment of status and consular processing.  

Adjustment of status is usually for a person who is already in the United States with a valid nonimmigrant visa status and has maintained a lawful visa status throughout their time within the United States. On the other hand, consular processing is for a person living outside the United States or for a person who is ineligible in adjusting their status in the United States. 

For a person who is residing overseas (outside the United States) or a person who is ineligible for an adjustment of status with the Form I-485 application, consular processing must be done to obtain the F-4 family preference green card visa status (i.e., lawful permanent resident). Consular processing usually involves the person attending an in-person interview at the U.S. consulate or embassy located in their home country. In certain circumstances, a person can do consular processing in another country as a “Third Country National.” 

After the interview approval at the U.S. consulate or embassy, the person would have to be admitted entry into the United States by the CBP officer at the border (usually at the airport). In other words, the person would have to physically enter the United States after their interview approval as the final step for their F-4 family preference green card visa status to be activated.

For a person who is already in the United States with a valid nonimmigrant visa, there are usually two options available to obtain their F-4 fourth preference family-based green card visa status (Lawful Permanent Resident):

(1) Adjustment of Status: this is the more commonly chosen option where the person would file a Form I-485 application to adjust their status without leaving the United States. The person would attend an in-person interview at a local USCIS office in the United States and the interview approval would serve as the final step for their F-4 fourth preference family-based green card visa status to be activated. 

The adjustment of status application (Form I-485) can be filed when the person’s priority date becomes current in the Visa Bulletin which means that there are no backlogs in visa availability for the person’s country of birth (not country of citizenship). This can happen while the green card petition (Form I-130) is still pending (i.e., before approval) with the USCIS or after the green card petition (Form I-130) is approved by the USCIS. It can also happen in concurrent filings (Form I-130 and Form I-485 sent together) where the person’s priority date is already current at the time of filing the green card petition (Form I-130) to the USCIS, however, this rarely happens for F-4 family preference green card petitions (siblings of U.S. citizens). 

When the adjustment of status application (Form I-485) is filed, applications for the employment authorization document (Form I-765, commonly known as the “EAD card”) and the travel document (Form I-131, commonly known as “Advance Parole”) can also be filed at the same time.  

The EAD card allows unrestricted employment where a person can change their job freely and can legally work for any employer in the United States, unlike a work visa such as an H1B visa which restricts a person to work for a specific employer in the United States. 

Advance parole allows a person to travel internationally while their adjustment of status is still pending. If a person has a pending adjustment of status application (Form I-485) with the USCIS but leaves the United States without advance parole and does not have a certain valid nonimmigrant visa status (H1B visa, H4 visa, L1 visa, L2 visa, K3 visa, K4 visa, V visa) that allows international travel, their adjustment of status will be considered abandoned. 

(2) Consular Processing: this is usually chosen if a person cannot show that they have maintained their lawful visa status in the United States or when the processing time for consular processing is much faster than the adjustment of status.

The spouse and dependent children (unmarried and under 21 years old) of the U.S. citizen’s sibling can also qualify for a green card by being listed as a derivative person under the sibling’s F-4 fourth preference family-based green card petition. 

The Child Status Protection Act (CSPA) protects certain children under the family-based green card petitions from aging out and losing their eligibility for the green card (or a particular visa category). Children can be seen as “aged out” if they turn 21 years old before their adjustment of status (Form I-485) with the USCIS or their application for an immigrant visa with the U.S. Department of State (i.e., consular processing) is approved. 

The CSPA determines the principal beneficiary (the person being sponsored) and their derivative children’s (the children of the person being sponsored) age by subtracting the amount of time USCIS took to approve the family-based green card petition from that person’s biological age at the time their visa becomes available. If the person’s CSPA adjusted age is under 21 years old when their priority date became current under their visa category, the person can retain that original status and their family-based green card petition will continue to proceed under that visa category. 

Children using the CSPA adjusted age must file for adjustment of status or consular processing to obtain their green card within one year of their priority date becoming current. If the child does not seek to change into the green card status within one year, then “extraordinary circumstances” must be shown to use that CSPA adjusted age.

Children of U.S. Citizens

The CSPA does not affect the children of U.S. citizens (who are never seen as aged out) because the law already allows them to preserve the status that they held when their family-based green card petition was filed. If a child of the U.S. citizen was unmarried and under 21 years old when their immediate relatives family-based green card petition was filed, they can still proceed with that original immediate relatives family-based green card petition even if they turn 21 years old. However, if the child of the U.S. citizen under the immediate relatives family-based green card petition gets married before obtaining their green card, they will be downgraded to the third family preference (F-3 Married children of U.S. citizens). 

CSPA Children of U.S. Citizen's Family Members

The CSPA mainly affects the derivative children of the principal beneficiary (sponsored family member’s child) under the third preference (F-3 Married children of U.S. citizens) or fourth preference (F-4 Brothers or sisters of U.S. citizens). For example, a U.S. citizen sponsoring a third preference family-based green card petition for his married daughter and her derivative husband and unmarried minor son: when the derivative unmarried minor son turns 21 years old, he loses his derivative status and his parents would need to file a new second-preference (F-2B) family-based green card petition (which cannot use an old priority date) for him after they obtain their own green cards unless he is protected by the CSPA adjusted age. 

Child Status Protection Action (CSPA) Age Calculation

In most cases, the Child Status Protection Action (CSPA) age is calculated by:

MINUS

MINUS

If the calculated age under the CSPA formula is under 21 years old, then the person can continue to file for an adjustment of status (Form I-485) or consular processing (Form DS-260) for their family-based green card as a “child” within one year of their priority date becoming current. On the contrary, if the calculated age under the CSPA formula is at or over 21 years old, then the person is not protected as a child under the CSPA and is seen as “aged out” of their family-based green card petition.

For example:

CHILD STATUS PROTECTION ACTION 兒童身份保護法(CSPA)eng

If the spouse or dependent children (unmarried and under 21 years old) of the F4 sibling of a U.S. citizen did not obtain a green card at the same time as the F4 sibling, they can still obtain their green card without filing a separate family-based green card petition (Form I-130) and they do not need to wait for a priority date to become current. In other words, the spouse or dependent children (unmarried and under 21 years old) of the F4 sibling of a U.S. citizen can obtain their green card (with no wait time) at a different time point than the F4 green card holder, however, their family relationship with the F4 green card holder must have existed before the approval of the F-4 family preference green card petition. 

There are 3 main ways for the family members of the U.S. citizen’s F-4 sibling to follow to join:

The F-4 fourth preference family-based green card petitions are for a U.S. citizen’s biological siblings, paternal half-siblings (same biological father but different mother), step-siblings, or adopted siblings. The spouse and dependent children (unmarried and under 21 years old) of the U.S. citizens siblings can also qualify for a green card by being listed as a derivative person under the sibling’s F-4 fourth preference family-based green card petition. 

The U.S. citizen must be at least 21 years old to sponsor an F-4 fourth preference family-based green card for their foreign sister or brother. If the foreign sibling is related to the U.S. citizen through a step-parent, the marriage of the U.S. citizen’s parents must have happened before the U.S. citizen or the foreign sibling turned 18 years old. If the foreign sibling is related to the U.S. citizen through adoption, the adoption must have happened before the U.S. citizen or the foreign sibling (adopted child) turned 16 years old.
