Overview of the B1 Visa for Nigerians
If you are travelling from Nigeria to the United States for business, you might think that you need a Visitor Visa. However, the Visitor Visa does not grant you the right to conduct business in the United States. The B1 Visa is a non-immigrant visa which allows you to perform temporary business-related duties in the US.
The B1 Visa can only be granted for a short period of time and only allows holders to travel to the US for specific business purposes.
If you are unclear if your upcoming business trip meets the B1 criteria then reach out to an immigration expert to guide you on ensuring the B1 Visa is the right option for you.
Eligibility Requirements for the B1 Visa for Nigerians
To travel to the United States under a B1 Visa, you must work in an eligible field. You are allowed to visit the US for consultations, litigation, contract negotiation, or participation in scientific, educational, professional, or business conventions.
You will not be able to use the B1 Visa for Nigerians if you plan on operating a business or consultancy from the U.S. The visa does not cover matters of gainful employment.
Some of the business purposes covered by the B1 Visa include:

- Service engineering – if you have specialized knowledge, you can travel to the US to install, repair, or replace industrial equipment or perform service engineering duties.
- Speaker or lecturer – so long as your payment comes from your home country and not a US source, you can visit the U.S. under a B1 Visa to perform lectures. You mustn’t accept payment from the US entity in the 6 months prior to your application, and you can only engage in these activities for more than 9 days.
- Business venture – you may survey areas for a potential site or business using the B1 Visa.
- Conference – you can visit the U.S. for a conference so long as you spend no longer than 9 days at a single institution. You cannot receive payment from a U.S. source for the conference, and you cannot receive payment from the institution in the 6 months prior to the conference.
- Research – you can use a B1 Visa to perform research that does not benefit a U.S. institution and if you will not receive payment from any U.S. entity.
- Medical elective – you are permitted to use the B1 Visa to study an elective clerkship at a U.S. medical hospital.
- Voluntary work – if you can prove your membership to a non-profit or religious charitable organisation, you can visit the U.S. to carry out charitable works.
- Working on the outer continental shelf – you can use the B1 Visa to work on the outer continental shelf, but you will be required to provide a letter from the U.S. Coastguard.

Processing Time and Cost of B1 Visa
Your B1 Visa will take between a couple of weeks and 2 months to process. In recent years, it has been taking longer to process B1 Visas due to increased demand.
The application fee for a B1 Visa is $185. You must be prepared to pay this amount before beginning the application process. In most cases, visa fees are non refundable if your application is refused.
B1 Visa Validity & Renewal
Each B1 Visa is assessed based on your circumstances. When you enter the United States, you will have an allotted amount of time for your duties and tasks. You can re-enter the country as many times as needed during this time, as it is a multi-entry visa. The maximum validity for a B1 Visa is 6 months.
You can renew your B1 Visa if you have genuine grounds to remain in the U.S. for business. To do this, you will need to pay the fee and fill out form I-529. You must apply for an extension before your B1 Visa expires.
The extension you can access depends on the nature of the business you must carry out in the United States, but cannot be above 6 months. You are not required to attend a second embassy interview during the reapplication process, but you must apply from your home country. There is a limit to how many times you can renew the visa, as you can only use it to stay in the US for 1 year maximum.
Can I Bring Family with Me on a B1 Visa?
If your partner, spouse, family member, or business partner wishes to accompany you to stay in the US, they can join you by applying for a B2 Visa. The B2 Visa is a visitor visa that allows your partner to live with you during your time in the United States. They cannot work in the United States under the B2 Visa and must not remain in the US once the B1 Visa holder has returned to Nigeria.
Can I Apply for a Green Card under a B1 Visa?
No, you are not allowed to apply for a Green Card under a B1 Visa unless unexpected conditions apply. If the following conditions apply, you can apply for a Green Card under a B1 Visa:
- You have married a US citizen
- You have acquired a new job and the employer is willing to sponsor you
- You have family members in the US and wish to join them
Unless you are married to a US citizen, or have an unexpected employment opportunity, you must return home to apply for your Green Card.
