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
Plan for at least three to four months with little or no salary between your last exam and your first full payslip, plus the cost of the new visa itself. In the UK the Graduate visa fee is £937 plus the health surcharge, and a decision usually takes up to eight weeks; in Canada you can work full time while a post-graduation work permit is processed only if you met set conditions when you applied. Build the budget from those dates, not from the job offer.
Where the gap comes from
For most Nigerian students abroad the money gap is not one problem but three that land at once. Student-job hours often stop or change when the course ends. The next visa costs money up front. And the first full salary, even after an offer, usually arrives at the end of the first complete month of work, sometimes later if payroll cut-off dates fall badly. Rent, transport, phone and the monthly transfer home keep running throughout.
The size of the gap depends on the route you are switching to and whether you are allowed to work while the application is decided. That is the first thing to pin down, from the official page for your country, before you plan a single number.
What the official rules say about working in the gap
United Kingdom: Graduate visa
GOV.UK (pages checked October 2026) says you must be in the UK on a current Student visa, your university must have reported that you completed the course, and you must apply before the Student visa expires. The fee is £937 and the Immigration Health Surcharge is £1,035 a year, which GOV.UK shows as £2,070 for two years and £1,552.50 for 18 months. A decision usually comes within eight weeks and you can stay while you wait. The visa lasts two years if you apply on or before 31 December 2026 and 18 months if you apply from 1 January 2027. On it you can work in most jobs, look for work and be self-employed, but you cannot claim most benefits. Many graduates later switch to a Skilled Worker visa, which has its own salary thresholds and fees.
Canada: post-graduation work permit
IRCC's help centre says you can work full time while waiting for a post-graduation work permit decision only if, when you applied, you had a valid study permit, had completed your programme, were eligible to work off campus without a permit, and had not worked off campus more than 24 hours a week during academic sessions. If you miss one of those, you may have no right to work until the decision, which turns the gap from weeks into months.
United States: OPT
The Department of Homeland Security's Study in the States page says post-completion OPT allows a total of 90 days of unemployment and that you must report employment changes to your designated school official within 10 days. The 90-day clock is a money issue as much as an immigration one: a job search that drags can force you to take the first offer.
Building the gap budget
Work from dates, not hopes. Write down the day your student work stops, the day you expect to apply, the likely decision date, a realistic start date and the first payday. Then cost each month.
Worked example (illustration only)
Chiamaka finishes a master's in Manchester in September and plans a Graduate visa application in October. Her figures, all labelled examples except the official fees:
| Item | Amount (example) |
|---|---|
| Graduate visa fee (GOV.UK) | £937 |
| Health surcharge, two years (GOV.UK) | £2,070 |
| Rent, October to January, 4 x £700 | £2,800 |
| Food, transport, phone, 4 x £350 | £1,400 |
| Support to parents in Enugu, 4 x £150 | £600 |
| Total needed before first full salary | £7,807 |
If she keeps a part-time job that pays £600 a month for those four months, she covers £2,400 and needs £5,407 in savings. If the first payday slips from the end of January to the end of February, add another month of rent, living costs and support: £1,200 more. Check the arithmetic on your own version line by line; the visa costs are the only fixed numbers.
Ways to narrow the gap
- Apply as early as the rules allow, so the decision period overlaps with your last weeks of study work rather than starting after them.
- Ask the new employer for its payroll calendar before you start. A start date just after a cut-off can mean almost two months before the first full pay.
- Tell family at home early that support may pause or shrink for a few months, and agree what is essential, such as school fees, and what can wait.
- Keep a separate pot for the visa and surcharge, so it is not spent on rent in a tight month.
- Avoid filling the gap with high-cost credit. Our guides on overdrafts and payday loans and sizing an emergency fund show why.
The naira side of the plan
Many students hold some savings in naira or receive help from parents in Nigeria. Converting all of it in one go when the visa bill arrives means accepting whatever the rate is that week. Spreading conversions over the months before the fee is due reduces the risk of one bad week. If parents are sending money, agree the amount and timing in writing between you so a delay at home does not collide with a visa deadline. Our article on a visa fees sinking fund covers the habit of setting aside a little each month for the next application.
Where Pryme fits
A Pryme Personal account can be opened from abroad and holds naira, pounds, dollars and euros with local details for each, so savings from home and wages abroad can sit side by side. Swap converts only when you choose, and the app shows the rate and the fee before you approve. Send covers transfers to family, and Savings Boxes can hold naira you plan to use at home later.
Questions people ask
How much money do I need to switch from a student visa to a Graduate visa?
The fixed costs are the £937 fee and the health surcharge (£2,070 for two years), per GOV.UK in October 2026. Add rent and living costs for the months before your first full salary.
Can I work while my PGWP is being processed?
Only if, when you applied, you had a valid study permit, had finished your programme, could work off campus without a permit and had kept within 24 hours a week off campus during sessions, according to IRCC.
How long can I be unemployed on OPT?
The Study in the States page gives a total of 90 days of unemployment on post-completion OPT.
Should I keep sending money home during the gap?
Many people reduce or pause support for a few months. Agree essentials with family early so nobody is surprised.
