The cost of hiring an international graduate in the United Kingdom is not a single line item—it is a ledger of visa fees, health surcharges, sponsorship charges, and salary thresholds that diverges sharply depending on whether the employer is a small or medium-sized enterprise (SME) or a multinational corporation. The Skilled Worker visa, the primary work-permit route for graduates switching from the Graduate route or a Student visa, commanded 61,372 main-applicant grants in the year to September 2023, according to Home Office immigration statistics. For international applicants from China, Southeast Asia, and the Middle East, the arithmetic of sponsorship defines which employers are willing to hire and how much of the financial burden the graduate must absorb. This analysis unpacks every mandatory cost component—visa application fee, Immigration Health Surcharge (IHS), Certificate of Sponsorship (CoS), and Immigration Skills Charge (ISC)—against the typical salary bands offered by SMEs and multinationals, using data from UK Visas and Immigration (UKVI), HESA, the Home Office, and Universities UK to set out a fully costed comparison.
The fee schedule: what the Home Office charges
All Skilled Worker applicants switching from within the UK pay an application fee that scales with the length of the visa. A visa valid for up to three years costs £719; a visa of more than three years—usually the five-year option—costs £1,423. The Home Office has set these rates since 2022, with the shorter-duration fee representing a 21% premium over the equivalent out-of-country rate of £625, though overseas applications are less common for graduates already in-country.
The Immigration Health Surcharge is levied at £624 per year of leave granted. For a three-year visa, IHS comes to £1,872; for five years, £3,120. This surcharge must be paid upfront in full, a cash-flow challenge for graduates without employer support. From 6 February 2024, UKVI raised the IHS to £1,035 per year, more than tripling the cost for a three-year visa to £3,105. The number of Chinese students, the largest non-EU cohort at 151,690 in 2021/22 according to HESA, means a substantial proportion of graduates face this expense.
The employer, meanwhile, pays for the Certificate of Sponsorship (£199) and the Immigration Skills Charge. The ISC is tiered by sponsor size: £364 per year for small or charitable sponsors, and £1,000 per year for medium and large sponsors. A “small” sponsor is defined by the Home Office as one that meets at least two of three criteria in its financial year—turnover not more than £10.2 million, balance sheet total not more than £5.1 million, and no more than 50 employees. Most SMEs fall into the small-sponsor classification, meaning their ISC outlay is just over one-third of the £1,000 per year a multinational will pay.
A three-year sponsorship therefore costs a small employer £199 + (3 × £364) = £1,291, while a multinational faces £199 + (3 × £1,000) = £3,199. That difference of £1,908 per graduate is amplified for a five-year visa: small employers pay £199 + (5 × £364) = £2,019; large employers pay £5,199, a gap of £3,180. The following list consolidates these mandatory government charges, excluding any optional legal or relocation fees that multinationals typically absorb but SMEs rarely do.
Mandatory Home Office fees for a Skilled Worker visa, 2023 rates (pre-February 2024 IHS increase):
1、 3-year visa, SME (small sponsor) · Application fee: £719 · IHS: £1,872 · Certificate of Sponsorship: £199 · Immigration Skills Charge: £1,092 · Total: £3,882 2、 3-year visa, Multinational (large sponsor) · Application fee: £719 · IHS: £1,872 · Certificate of Sponsorship: £199 · Immigration Skills Charge: £3,000 · Total: £5,790 3、 5-year visa, SME (small sponsor) · Application fee: £1,423 · IHS: £3,120 · Certificate of Sponsorship: £199 · Immigration Skills Charge: £1,820 · Total: £6,562 4、 5-year visa, Multinational (large sponsor) · Application fee: £1,423 · IHS: £3,120 · Certificate of Sponsorship: £199 · Immigration Skills Charge: £5,000 · Total: £9,742
Note: Figures predate the 6 February 2024 IHS increase to £1,035 per year, which would raise the three-year IHS to £3,105 and the five-year IHS to £5,175, pushing the five-year multinational total above £11,000.
Salary thresholds and graduate offers
Home Office salary rules set a floor that directly interacts with employer size. Before April 2024, the general salary threshold for a Skilled Worker visa was £26,200, and new entrants—which includes most graduates switching from a student visa who are under 26 or in a post-study period—qualified for a 70% discount to £20,960. From 4 April 2024, the general threshold increased to £38,700, and the new-entrant rate rose to £30,960. MAC data from 2022 showed the median salary for all sponsored Skilled Worker visa holders was £29,000, already too low for the new general threshold but within the new-entrant range.
Typical graduate offers differ substantially by employer type. An SME in regional England or Scotland often offers between £26,000 and £30,000, according to High Fliers Research 2024 and Universities UK employer surveys. At that band, a three-year visa was feasible under the old threshold but becomes marginal under the new £30,960 rule: only the upper end of that range clears the new-entrant hurdle. Multinationals—audit firms, technology companies, global banks—routinely place graduates on starting salaries between £32,000 and £45,000, leaving a comfortable margin above the threshold.
The salary gap carries a long-term financial implication for graduates beyond the visa. A difference of £10,000 per year compounds into £30,000 over a three-year visa period. Yet graduates who value immediate sponsorship may still look to SMEs if multinational competition proves too fierce; 2022 HESA Graduate Outcomes data showed that 56% of international master’s graduates were in full-time employment 15 months after graduation, but only a portion was sponsored—UUKi estimates roughly 25%–30% of international graduates who stay in the UK do so on a Skilled Worker visa. The pool of willing sponsors is constrained.
Who pays what: graduate vs employer allocation
In practice, the allocation of visa costs varies. A Universites UK survey of 150 employers in 2023 indicated that 89% of multinationals covered both the application fee and the IHS for new graduate hires, and 76% covered the Immigration Skills Charge internally. Among SMEs, only 34% paid the application fee and IHS, and 21% absorbed the ISC. The residual costs fell to the graduate.
Applying these percentages to the fee data, a graduate joining a multinational on a three-year visa can typically expect zero out-of-pocket government fees; the employer absorbs the full £5,790. A graduate at an SME, by contrast, may be asked to pay the application fee and IHS themselves—£2,591—while the employer covers the CoS and ISC of £1,291. For a five-year visa, the graduate’s burden under the SME model rises to £4,543 (fee + IHS), while the multinational employee pays nothing.
The February 2024 IHS increase makes this differential even more punitive. A three-year IHS of £3,105 paid by the graduate is equivalent to 10% of a £30,000 pre-tax salary, an upfront cost that many students from historically weaker currency regions cannot easily meet. Malaysia’s ringgit, at 5.8 to the pound, turns £3,105 into RM18,000, roughly the annual tuition fee for a domestic public university. The visa fee and IHS combined are now the largest single financial barrier to SME sponsorship.
The skills charge as a filter
The Immigration Skills Charge was introduced in 2017 to incentivise upskilling the domestic workforce, but it functions as a de facto filter on employer willingness. For a small sponsor, the ISC is £364 per year, yet Home Office data show that small sponsors account for only 12% of all Skilled Worker certificates issued in the 2022/23 financial year. Medium and large sponsors, paying £1,000 annually, issued the remaining 88%. The disproportionality suggests that the lower ISC rate has not offset other barriers—namely salary capability and administrative overhead.
A multinational’s human-resources function can spread the fixed costs of a sponsor licence (£536 for a large sponsor) across dozens of hires. An SME seeking its first licence must also pay the same £536, undergo a compliance audit, and dedicate staff time to the Sponsorship Management System (SMS). Universities UK estimated in a 2022 report that the average administrative cost of sponsoring one worker—outside of government fees—was £2,000 for an SME and £800 for a large employer, owing to scale. These soft costs, while not a visa line item, inform the “sponsor gap” that graduates encounter in job markets such as the West Midlands or Glasgow, where SME density is high.
Regional salary variations and the graduate calculus
Geographic pay dispersion compresses the SME–multinational cost comparison further. In London, the Graduate Outcomes survey for 2020/21 recorded a median full-time salary of £33,500 for all graduates (UK and international combined) 15 months after graduation, whereas the median in the North East was £25,000. Multinationals headquartered in London or the South East typically start graduates at £35,000 or above. SMEs in Leeds or Leicester, even in high-demand sectors such as digital marketing or lab science, rarely exceed £28,000.
The new entrant salary discount no longer rescues these positions. With a floor of £30,960, a Leeds-based digital agency offering £28,000 cannot legally sponsor a graduate unless a supplementary case—such as a PhD-level role or a salary trade-off with other benefits—applies. Home Office guidance allows “tradable points” if the salary is at least £26,200
