Employment Law Digest June 2026: When immigration becomes a bottleneck

For businesses that rely on international talent, sponsorship is becoming increasingly difficult to navigate.

Over the last 12 to 18 months, we have seen growing scrutiny of sponsor licence applications, lengthy delays in Certificate of Sponsorship (CoS) allocation requests and decisions that can be difficult to reconcile with published Home Office guidance. The result is increased uncertainty, operational disruption, additional cost and rising frustration for sponsors trying to recruit and retain key talent.

While sponsor licence refusals often attract attention, many of the most significant challenges we are seeing arise after a licence has been granted.

Increased scrutiny across the sponsorship system

Historically, sponsor licence applications were largely evidence-based exercises. If an organisation could demonstrate that it was genuine, trading and met the relevant requirements, approval would usually follow.

Increasingly, however, sponsors are finding that the Home Office is looking beyond the documentary requirements and scrutinising wider issues such as recruitment plans, vacancy requirements, the organisation’s UK operations and the overall credibility of its sponsorship needs.

In our experience, this has introduced a greater degree of subjectivity into the decision-making process. Sponsors can ostensibly meet the formal requirements yet still face extensive requests for additional information, lengthy delays or adverse decisions based on broader Home Office concerns about their genuineness, compliance or UK plans.

This shift creates uncertainty for businesses. Organisations are no longer simply being asked to demonstrate compliance with the rules; they are increasingly having to justify the commercial rationale behind their recruitment strategy, workforce planning and, in some cases, their wider UK presence.

CoS allocation delays are creating real business problems

This is a particular issue we have seen in practice in relation to CoS allocation requests.

Many sponsors continue to view allocation renewals and increase requests as administrative exercises. Increasingly, however, they appear to be treated as an opportunity for the Home Office to undertake a wider desktop review of the sponsor’s compliance position.

We are seeing requests for significant volumes of information, often extending well beyond the immediate allocation request itself. In some cases, sponsors are asked to provide extensive evidence relating to recruitment activity, organisational structure, sponsored (and UK) workers and their wider business operations. What’s worse, sponsors are usually given a very tight deadline for responding to such requests (usually within five working days).

Frustratingly, it is also not uncommon for sponsors to receive repeat requests for information that has already been provided, resulting in additional cost, management time and delay.

In several recent cases, we have submitted hundreds of pages of supporting documentation in response to information requests, only for the allocation to be granted shortly afterwards. While robust compliance checks are an important part of the sponsorship system, experiences such as these can leave sponsors questioning whether the information provided has been fully considered before responses are issued.

One of the key practical consequences of this approach is delay. We are increasingly advising sponsors who have identified the right candidate, agreed start dates and planned projects around expected hires, only to find recruitment placed on hold while allocation requests remain outstanding.

In other cases, sponsors are facing uncertainty where existing sponsored workers need to extend their permission to remain living and working in the UK but cannot be assigned a CoS because an allocation request remains outstanding.

For many businesses, the impact is immediate. Recruitment plans are delayed, projects are disrupted, management time is diverted and uncertainty grows for both employers and employees while decisions remain outstanding.

When policy and practice don’t align

One of the most frustrating aspects of these cases is that Home Office guidance often anticipates the problem.

For example, where a sponsor is awaiting a CoS allocation decision due to delays by the Home Office, the guidance provides for applications to be placed on hold rather than refused because a CoS cannot yet be assigned. The principle is straightforward: applicants should not be disadvantaged by delays within the sponsorship system itself.

Yet in practice we have seen and continue to see cases where applicants are asked to provide a valid CoS within a short timeframe despite the relevant allocation request still being under consideration elsewhere within the Home Office.

Where this happens, early intervention can make a significant difference.

We have been doing a lot of work for clients and their employees who have faced this situation, engaging with the Home Office to highlight relevant rules and policy provisions and engaging with decision-makers before matters escalate. In many cases, this can result in applications being held pending the allocation decision and avoid unnecessary refusals, invalidity decisions and wider right to work concerns.

Acting early matters

The common thread running through many of these cases is that delay often creates as big a problem as the underlying immigration issue itself.

Sponsors that take advice early are generally in a much stronger position to manage risk, protect recruitment plans and minimise disruption to their workforce. If problems arise, well-prepared representations can often resolve issues before they have a wider operational impact.

In some cases, more formal action may be required. Pre-action correspondence can be an effective way of prompting reconsideration where decisions appear inconsistent with policy or where delays have become unreasonable.

Judicial review remains an important safeguard, but it is rarely a sponsor’s preferred option. It can be costly, time-consuming and resource-intensive. However, we are increasingly helping clients to initiate Judicial Review processes to challenge prolonged delays or decisions, particularly those that appear inconsistent with the Home Office’s own guidance and policies.

What should sponsors be doing now?

Sponsors should not assume that meeting the documentary requirements alone will guarantee a smooth process. Forward planning has become increasingly important, particularly where future recruitment or visa extension applications depend on additional CoS allocations.

Businesses should also seek advice early where issues arise. For businesses that rely on international talent, the risk of delays, uncertainty and operational disruption can be as important as the risk of a refusal.

If your organisation is experiencing problems with a sponsor licence application, CoS allocation request or requests for information from the Home Office, our immigration team can help assess the position, engage with the Home Office where appropriate and advise on practical options to keep your recruitment plans and workforce management on track.
