AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Nigerian employees coming to the UK for meetings, training or an internal project usually apply for a Standard Visitor visa, which GOV.UK lists at £135 for up to 6 months. The Immigration Rules allow business activities such as meetings, negotiating contracts, site visits and, for staff of an overseas company, advising, training and sharing skills on an internal project with UK colleagues of the same group, but not doing paid or unpaid work for a UK company.
Bringing your Lagos finance lead to London for the year-end close, or your Abuja sales team to a trade fair, is one of the most useful things a UK-Nigeria business can do. It is also where companies get the visa wrong, usually by describing a visit that sounds like a job. The rules are specific about what a business visitor may and may not do.
Which visa
GOV.UK's visa checker says, by nationality, whether a visitor needs a visa, an ETA or neither; Nigerian staff visiting on business generally use the Standard Visitor visa. GOV.UK lists the fee at £135 for a visit of up to 6 months, and longer-term visit visas exist for frequent visitors (the Home Office fee table lists 2, 5 and 10-year options). Applicants can apply up to 3 months before travel and must show they will leave at the end of the visit, can support themselves (or someone else will fund the trip) and can pay for the return journey.
What a business visitor may do
Appendix Visitor of the Immigration Rules sets the permitted activities. Under PA 4, any visitor may:
- attend meetings, conferences, seminars, interviews and workshops;
- give a one-off or short series of talks, if not organised as commercial events for profit;
- negotiate and sign deals and contracts;
- attend trade fairs for promotional work only, without directly selling;
- carry out site visits and inspections;
- gather information for their employment overseas;
- be briefed on a UK customer's requirements, provided the work for the customer is done outside the UK;
- do remote work for their overseas job, provided that is not the main purpose of the visit.
Under PA 5.1, an employee of an overseas company may also advise and consult, trouble-shoot, provide training and share skills and knowledge on a specific internal project with UK employees of the same corporate group. PA 5.2 allows limited client-facing work only where it is incidental to the employment abroad and the project is being delivered by the UK branch. PA 6 lets an internal auditor carry out audits at a UK branch of the same group.
What a business visitor must not do
GOV.UK is clear that a Standard Visitor cannot do paid or unpaid work for a UK company or as self-employed, apart from permitted paid engagements. Filling a vacancy, covering for an absent UK employee, or doing productive work directly for UK clients goes beyond a visit. If the plan is for the person to work in the UK for months, look at a work route instead (see Skilled Worker sponsorship or the Global Business Mobility route).
The invitation letter
The GOV.UK visitor page does not list an invitation letter as a required document. Employers still commonly provide one, because it helps the applicant show the purpose of the visit and who is paying. A useful letter, on company letterhead and signed by a director or HR lead:
- names the employee, their job, and the Nigerian employing company and its relationship to the UK company;
- states the dates and the purpose in the words of the permitted activities (for example, 'training UK colleagues on the group's reconciliation process, an internal project');
- lists the main meetings or the programme;
- says who is paying for travel and accommodation and confirms the employee stays on the Nigerian payroll;
- confirms the employee is expected back at work in Nigeria on a stated date.
Keep the letter consistent with the application form. A letter that describes 'working on our London client account' undermines an otherwise sound application.
Common situations
- Year-end close in London
- Training UK colleagues on the group's process, or being trained, fits PA 5.1 as an internal project. Preparing the UK company's own accounts as its finance team would is closer to work.
- Trade fair stand
- Promoting the group's products fits PA 4(d). Taking orders and selling directly from the stand does not.
- Client kick-off
- Being briefed by a UK customer fits PA 4(g) if the work for that customer is then done in Nigeria.
- Internal audit visit
- An internal auditor checking the UK branch of the same group is covered by PA 6.
- Covering a vacancy
- Standing in for a UK employee for weeks is work, not a visit, and needs a work route.
When an activity sits near a line, describe it accurately rather than vaguely. Officers compare the application, the letter and what the applicant says at the border.
What to check first
- That every planned activity fits PA 4, PA 5 or PA 6.
- Passport validity for the whole stay.
- The employee's evidence of ties to Nigeria: employment letter, payslips, bank statements.
- Who pays, and that it is stated the same way everywhere.
Where Pryme fits
Travel costs are easier to evidence when they are paid from the business. A Pryme Business Account can pay flights and hotels in pounds and the employee's naira costs at home, with each payment recorded and a verifiable statement available through VerifyDoc.ai (receipts). The Chief of Staff agent can prepare the trip budget and approvals for a director to sign off.
Questions people ask
Does a Nigerian employee need an invitation letter for a UK business visit?
GOV.UK does not list one as required, but a clear letter from the UK company stating the purpose, dates and who pays usually helps.
Can a Nigerian visitor attend training in the UK?
Yes. Employees of an overseas company may receive and give training and share skills on an internal project with UK colleagues of the same group.
How much is a UK business visit visa from Nigeria?
GOV.UK lists the Standard Visitor visa at £135 for up to 6 months. Longer-term visit visas cost more.
Can my Lagos staff work from our London office on a visit visa?
They can do remote work for their Nigerian job only if that is not the main purpose of the visit. They cannot do work for the UK company.
