    Overview of the F4 Visa for Nigerians

    The United States F4 Visa gives immigration status to eligible brothers and sisters of US citizens. It belongs to the second category of Family Immigration, which is Family Preference. The first category, Immediate Relative, is reserved for spouses, children, and parents of US lawful permanent residents.

    US citizens do not necessarily need to have full or half biological siblings to file an application for the F4 Visa. Adopted siblings and stepsiblings can move to the US if they meet the additional criteria.

    For adopted siblings, this means the adoption must have occurred before the 16th birthday of the adopted individual. Stepsiblings must prove their parents married before the US citizen turned 18.

    Once the visa is acquired, siblings can establish a life in the US including work, studies and access to healthcare. If they have dependents, they can live together in the US lawfully.

    How Long is the F4 Visa Processing Time?

    As with any US Visa, processing times vary significantly between applications. The official estimated waiting time for this visa is 1-10 years.

    The F4 Visa is particularly competitive as a preference for Family Green Cards is given to immediate relatives instead of siblings, so F4 Visa waiting times are notoriously long.

    Short waiting times are more likely if the application is straightforward, the applicant submits the form at a quiet time and all requested information is provided in a timely manner.

    It isn’t always possible to keep waiting times short as there can be expected and unexpected delays. The main expected delay is linked to the cap on F4 Visas. There is limited availability which means that applicants are competing for visas each year.

    Unexpected delays may include difficulties with application processing, suspicious documents and unforeseen surges in applications.

    Submitting the application quickly is key to obtaining a visa as soon as possible. The fastest route is to hire an IAS immigration solicitor who is experienced with each stage of the process by calling +44 (0) 331630092.

    How Much Does the F4 Visa Application Cost?

    The Green Card for brothers and sisters of US citizens includes the following fees:

    • Form I-130 filing fee ($535)
    • Form DS-260 processing fee/USCIS immigrant fee ($325)
    • Medical examination and vaccination fee (varied)

    Some applicants will be required to pay:

    • Translation fee (varied)

    The medical examination and vaccination costs will vary depending on the institution you visit in Nigeria.

    The reason the translation fee varies is that it is the responsibility of the applicant to find a qualified translator for any documents that are not written in English. The fees will be different for each translator. Applicants whose documents are all written in English do not have to pay this fee.

    Who is Eligible for the F4 Visa?

    As the F4 Visa is a Family Visa, both the US citizen and their sibling must meet the eligibility criteria.

    The US citizen must be:

    • A US resident with a valid address
    • 21+ years old
    • In possession of documents proving an authentic sibling relationship with the applicant

    The sibling must be under 21 years old and be able to prove that their brother or sister is a citizen of the USA.

    If you’re in Nigeria and would like to go to your sibling in the US, we can guide you through the process.

    How to Apply for the F4 Visa

    File a Petition

    The first step of applying for a F4 Visa is to file a petition. The US citizen sibling must file Form I-130, Petition for Alien Relative to confirm that they want their brother(s) or sister(s) to move to the US as a permanent resident.

    File the Online Form

    When a petition is accepted, the Nigerian citizen can file Form DS-260 (Immigrant Visa Electronic Application) with the information they have received from the National Visa Center (NVC). This includes their invoice number, case number and beneficiary ID number.

    Responses to Form DS-260 questions and prompts must be highly accurate and written in English. The requested information includes:

    • Personal details
    • Contact details
    • History of home addresses starting from the age of 16
    • Family information

    Submit the Correct Documents

    Before the form is submitted, certain documents must be submitted. The desired documents will be outlined in the application. All applicants must provide the following documents:

    • Confirmation of online application
    • Birth certificate
    • Copy of current passport

    Certain applicants will need to attach the following:

    • Form I-864 (Affidavit of Support) (including supporting financial documents)
    • Certified court or prison record (for any convictions)
    • Military records (including proof of honourable discharge)
    • Police clearance certificate (for over-16s who have lived in the US for 6+ months)
    • Proof of marital status (marriage certificate, divorce certificate or death certificate)
    • Form I-864A (Contract Between Sponsor and Household Member) (including supporting financial documents)

    After the successful submission of these documents, applicants will see a confirmation page that they must save and send to the NVC.

    Schedule a Medical Appointment in Nigeria

    All Nigerian F4 Visa applicants must schedule vaccinations and a general medical examination before being permitted to live in the US permanently. The appointment must occur at least two weeks before the F4 Visa interview.

    Furthermore, the doctor performing the examination and vaccinations must be approved by the US Consulate General.

    Schedule Visa Interview and Prepare Documents

    F4 Visa interviews can be booked at a US Consulate or Embassy in Nigeria. Applicants must bring the following documents to interview:

    • Confirmation of Form DS-260 submission
    • NVC interview letter
    • Proof of sibling relationship to US citizen (birth certificates, photographs and/or letters)
    • Form I-864 (Affidavit of Support) for each financial sponsor (with relevant W-2s and a photocopied IRS transcript/most recent US federal income tax return)
    • Original and photocopied birth certificate of US citizen sibling
    • Proof of US citizen’s immigration status in US (lawful permanent resident card, photocopy of valid passport or naturalisation certificate)
    • Two colour passport-sized photographs of identification
    • Original and photocopied birth certificate of applicant and any dependants
    • Valid passport with a photocopied biographic page (must be valid for at least six months after proposed arrival in US)
    • Additional forms of identification (expired passports, voter registration cards, school reports etc)

    If relevant, original military records, adoption papers and court/criminal records may be requested along with photocopies.

    Let us assist you through the complexities of obtaining an F4 visa

    What to Expect During the F4 Visa Interview

    During the F4 Visa interview at a US Embassy or Consulate, consular officers assess applications for eligibility and authenticity. They primarily do this by asking questions about topics including:

    • The applicant’s reasons for moving to the US
    • The sibling relationship
    • History of US travel
    • Criminal involvement
    • US citizen sibling
    • Dependants

    Applicants must speak truthfully as suspicious information will be investigated and could result in rejection from the F4 Visa.

    What Happens If my F4 Visa Application is Denied?

    There is never a guarantee that F4 Visa applications will be approved, even for genuine siblings of US citizens.

    The main reasons for refusal are inadmissibility and fraudulent information, though other common reasons include missing documents, delayed responses and ineligibility.

    When an F4 Visa is denied, only the US citizen petitioner can appeal the decision. The Nigerian applicant may re-apply for this visa, but it is strongly recommended that they work with an IAS lawyer to avoid falling victim to the same issues again.

    Getting an F4 Visa as a Temporary Immigrant

    US citizens with temporary resident siblings can petition for an Adjustment of Status (AOS) for their sibling by filing Form I-485. They must also submit the following online forms:

    • I-864 (Affidavit of Support)
    • I-693 (Report of Immigration Medical Examination and Vaccination Record)
    • I-765 (Application for Employment Authorization)
    • G-325A (Biographic Information (for Deferred Action)

    If this adjustment is approved, the sibling is permitted to reside in the US permanently and obtain the F4 Visa.

    For Nigerian individuals whose immigration status is close to expiring, or who are illegal US immigrants, it may be possible to acquire an F4 Visa by filing Form I-485 (Adjustment of Status to Permanent Residency) with supporting evidence of eligibility.

    Frequently Asked Questions

    All Family Green Card holders, including F4 Visa holders, can travel outside the US lawfully. There are limitations such as having to return to the US within the year and not going on permanent trips.

    65,000 F4 Visas are offered to brothers and sisters of US citizens each year. Not all visas have caps, so the fact that F4 Visas are limited means that it is all the more important to submit a high-quality application.

    Individuals who have been in possession of an F4 Visa for 5+ years and have been physically present in the US for at least 30 months out of this period can apply for US citizenship.

    They must check that they meet the full eligibility criteria before submitting Form N-400 (Application for Naturalization).

    I spoke with Saima Jabeen about the areas where I needed assistance. She was very helpful and provided me with clear and useful information. I was satisfied with the support and guidance she provided.
    Very positive professional experience. My immigration advisor Mariam Adebayo helped my wife successfully obtain her Spouse visa extension. At the very start we had a face to face meeting at their Oldham office to discuss our needs, explain the process and what evidence we would need. We later received a written confirmation of advice laying out everything from timeframes, fees and documentation needed. Through out we had video calls and regular emails for updates and when our input was needed, Mariam even uploaded all of the extensive evidence as part of the application process which I was very happy with as I know from my own experience this can take a while. I would definitely use IAS again, don't be fooled in to opting for cheaper options, I came to IAS after a poor experience with a different company and so came back as I'd had a good experience with IAS way back in the 90's so know that they have been around for a years. Thank you IAS Oldham and Mariam Adebayo.

    I would like to express my heartfelt gratitude to Abdul Mutee for everything he has done throughout my visa process. The past year was incredibly stressful, especially after facing two Canada visa refusals. During this difficult time, Abdul Mutee did not simply provide guidance; he actively worked on my case and supported me every step of the way when I felt overwhelmed and uncertain about my future. Thanks to his dedication, hard work, and continuous support, my UK visa has now been approved. This approval allows me to continue my education and pursue my dream of becoming a dentist. I truly believe that this achievement would not have been possible without his assistance and commitment. Abdul Mutee played a significant role in making this outcome possible, and I am deeply thankful for the relief, hope, and opportunity he has given me. His efforts have made a lasting impact on my life, and I will always be grateful for everything he has done. I will never forget the support, encouragement, and professionalism he showed throughout this journey. Abdul Mutee's help has made a real difference in my future, and I sincerely appreciate all of his hard work and dedication.

    I used IAS for my first visa and I must say it wasn't a pleasant experience. We didn't receive all the information, we would find out about things along the way and it made it all very stressful even though the application was successful. We were a bit reluctant to do it again for the renewal but went for it anyway due to lack of time. Anne Liu was out caseworker and she was terrific! Super on top of the case! She would review the docs very quickly after we submitted it and would immediately tell us what would be missing. She made herself available when we needed her all the way up to the appointment. Definitely made the experience more stress free!

    Anne has been nothing short of exceptional throughout mine and my husbands immigration query. From the very start, she was informative, diligent, understanding, compassionate and helpful. Any immigration matter is delicate and stressful for those involved and Anne met us with patience and kindness throughout, keeping us well informed and calm when everything felt tricky. We honestly couldn’t have asked for a better advisor and we are so grateful for everything that she did for us to get my husbands spousal visa approved. Her dedication and commitment proved enormously valuable and I will be welcoming my husband home tomorrow because of her. Without a doubt we will use her again in 2029 when required and we cannot recommend her enough for anyone going through a similar matter. Thank you Anne, from the bottom of our hearts, we will always appreciate you and remember your engagement fondly.

    Everybody at IAS has been professional and helpful. In particular my case worker, Elena Ampova simply could not have been more patient, friendly and approachable and knowledgeable. Nina and I found it difficult to supply information in the file formats required and Elena spent hours helping us. And the end result has been that my fiancée, Nina's visa application has been approved. Perfect service and a perfect result.

    I cannot recommend Mariam Adebayo at IAS highly enough. She supported me thoroughly from A–Z throughout my UK Global Talent Visa journey, ultimately helping me successfully obtain my visa through the Exceptional Talent route. From the very beginning, Mariam was incredibly professional, knowledgeable, patient, and attentive. She guided me through every stage of the process with clarity and reassurance, always making sure that my application was as strong and comprehensive as possible. What stood out most was how consistently she went above and beyond her dedication, responsiveness, and genuine commitment to achieving the best possible outcome for me were evident throughout the entire journey. Thanks to Mariam’s exceptional support and hard work, I now have the incredible opportunity to continue developing and practicing my talent in the UK. This is a truly significant milestone in my professional and creative journey, and I am extremely grateful for the role she played in making it possible. Mariam is an outstanding caseworker and a true asset to IAS. I wholeheartedly recommend her to anyone seeking immigration support, particularly those applying through the UK Global Talent route. Thank you, Mariam, for your dedication, guidance, and for helping turn this opportunity into a reality.

    My case worker Mariam Adebayo guided my fiancee, a Belarusian national and me on what documentation and translations were required and checked through everything at every stage. She then made the application on our behalf for a fiancee visa. The application was 100% successful with no other documentation required or any queries raised by UKVI. Mariam further assisted in getting our spouse visa after our marriage in May 2026. Again 100% successful. Mariam has been extremely thorough in every part of our fiancee and spouse visa. Everything went through without a hitch! I have no hesitation in recommending her. Peter and Teresa Welch.
