Skilled Worker Visa Application Process
Once you have a qualifying job offer and a valid Certificate of Sponsorship, the next stage is to prepare and submit the application. The exact process depends on whether you're applying from outside the UK, switching, extending, or changing employer — and the Home Office assesses every application against three groups of requirements: validity, suitability and eligibility.

In brief
- With a qualifying job offer and valid Certificate of Sponsorship, the next stage is to prepare and submit the application.
- The exact process depends on whether you apply from outside the UK, switch, extend, or change employer.
- Every application is assessed against validity, suitability and eligibility.
- The guide walks through the step-by-step process and documents.
Before you apply
Before submitting, make sure the main Skilled Worker requirements have been addressed. This includes checking that:
- You are at least 18
- Your employer holds the required sponsor licence
- You've been assigned a valid Certificate of Sponsorship
- Your job is eligible
- The correct occupation code has been used
- The job meets the applicable skill level
- Your salary meets the threshold and going rate
- You meet the applicable English requirement
- You meet the financial requirement where required
- Any additional requirement for your circumstances is addressed
This is not an exhaustive list of every Immigration Rule that may apply — it's the set of requirements most applications need to satisfy.
The step-by-step process
The route from CoS to decision, in order. Several steps have their own detailed guide — follow the links to check them properly before you apply.
- Step 1Check you can apply
Confirm your circumstances allow the type of application you intend — entry clearance, switching, extending, or changing employer. Different requirements apply to each.
- Step 2Obtain a Certificate of Sponsorship
Your employer assigns an electronic CoS via the SMS; you provide its reference in the application.
- Step 3Check the CoS assignment date
It must have been assigned no more than 3 months before the date of application — a CoS can't be kept indefinitely for a future application.
- Step 4Check occupation & skill level
From 22 July 2025, entry-clearance and switching applications are generally limited to qualifying RQF Level 6 occupations, or eligible TSL/ISL jobs (transitional provisions aside). See occupation codes.
- Step 5Check your salary
Compare basic salary, the general threshold, the going rate, your hours and the salary option — meeting one headline figure is rarely enough. See salary requirements.
- Step 6Check your English requirement
Usually B2 (CEFR) in all four skills from 8 January 2026; certain existing workers keep transitional B1. See English requirement.
- Step 7Check the financial requirement
Where it applies, £1,270 held for 28 days — unless you're auto-exempt (12 months in the UK) or your A-rated sponsor certifies maintenance. See financial requirement.
- Step 8Prepare identity documents
Biometrics, where provided, must be verified against a valid passport or travel document. Requirements depend on the application process available to you.
- Step 9Tuberculosis certificate (if required)
Can be required in relevant entry-clearance cases — checked against the dedicated TB rules, not assumed.
- Step 10Criminal record certificate (if required)
Applies to certain applications depending on the sponsored employment — not to everyone.
- Step 11ATAS (if it applies)
Some roles/research need an ATAS certificate; a Defined CoS can be rejected where the job fails the skill-level requirements, including ATAS.
- Step 12Scholarship consent (if required)
If you had government/international scholarship funding (fees + living costs) in the 12 months before applying, written consent is needed — separate from the financial requirement.
- Step 13Submit the correct application
Meet the validity requirements (correct process, required identity information). An invalid application may be rejected rather than considered on its merits.
- Step 14Pay the application fee
The relevant fee (which can vary by application type) forms part of the validity assessment. We confirm current amounts rather than quote a figure that may be out of date.
- Step 15Pay the Immigration Health Surcharge
Most applicants pay the IHS where applicable. Qualifying Health and Care Visa applicants are exempt and benefit from lower fees.
- Step 16Verify identity & provide biometrics
Depending on the process, this may involve biometrics and your passport/travel document; biometrics must correspond with the valid identity document supplied.
- Step 17Provide supporting evidence
Tailored to your circumstances — there is no single universal document list. A personalised checklist is preferable to a generic one.
Documents & further evidence
The evidence required depends on your circumstances — there is no identical list for every applicant. Depending on the case, it may need to establish identity, sponsorship, English, the financial requirement, qualifications, ATAS, a criminal record certificate, a TB certificate, scholarship consent, or previous immigration status where a transitional provision is relied on. Several of these are governed by separate rules — Appendix English Language, Appendix Finance and Appendix ATAS — so a personalised checklist beats a universal one. See our Skilled Worker documents checklist.
Documents not in English may need an appropriate English translation that satisfies the relevant evidential requirements. And UKVI can request further information and verify documents — so ensure information is accurate, documents are genuine, employment details are consistent with the CoS, and any requested evidence is provided within the deadline given.
Applying from outside the UK
If you're outside the UK, you'll normally make an application for entry clearance, and your sponsor will generally need to assign a Defined CoS before you apply. Pay particular attention to the requirements most relevant to overseas applications:
- Financial requirement
- TB certificate where applicable
- Criminal record certificate where applicable
- ATAS where applicable
- Identity & biometric requirements
Switching to Skilled Worker from inside the UK
Not everyone in the UK can switch directly into the route — see our full switching to a Skilled Worker visa guide for the by-route detail. You cannot switch if you have, or were last granted, permission as:
- a Visitor
- a Short-term Student
- a Parent of a Child Student
- a Seasonal Worker
- a Domestic Worker in a Private Household
- permission granted outside the Immigration Rules
Where switching isn't permitted, you may need to leave the UK and make the appropriate entry-clearance application instead.
Switching from the Student route
Additional rules apply — you must satisfy one of the relevant study conditions, which depending on the circumstances can include:
- Having completed the course the CAS was assigned for
- Having completed an eligible changed course
- Having a course finishing before the CoS employment start date
- For a PhD, having completed at least 24 months of study
"Completed" doesn't necessarily mean "passed". The guidance explains the applicant must have studied to the end of the course — the result is a separate matter.
Extending a Skilled Worker visa
Existing Skilled Workers can apply for further permission where the requirements are met — but it's not an automatic renewal. You should still check sponsorship, occupation eligibility, salary, the English requirement, any applicable transitional provisions, and your current immigration status. Some existing workers benefit from transitional rules that don't apply to new applicants. See our full Skilled Worker visa extension guide.
Changing employer
Moving to a different Skilled Worker sponsor normally means a change-of-employment application supported by a new CoS. Don't treat a new sponsored role as automatically covered by your existing permission — the new job must satisfy the Skilled Worker requirements applying to the new application. See changing employer on a Skilled Worker visa.
How the application is assessed
The Home Office considers three main categories:
Was it properly made?
Correct process, required identity information, fee paid. An invalid application may be rejected without a full eligibility assessment.
Any reason to refuse?
Immigration-law breaches and general grounds for refusal — separate from job or salary.
Do you qualify?
Sponsorship, skill level, salary, English and the other applicable Skilled Worker requirements.
An application is more than an online form
Your sponsorship, occupation code, salary, English position, finances and supporting evidence should all be checked before you submit.
Common application mistakes
- Applying before checking the occupation code — an incorrect code can affect both job eligibility and salary.
- Applying with an old CoS — it must normally have been assigned no more than 3 months before the application.
- Checking only the headline salary — both the general threshold and the occupation going rate may need to be met.
- Using the wrong English requirement — most new applicants need B2, while certain existing workers can remain on B1.
- Forgetting the financial requirement — those in the UK less than 12 months may need funds or valid sponsor certification.
- Trying to switch from a prohibited route — Visitors and certain other categories cannot switch in-country.
- Student applicants applying too early — the study-completion or timing condition must be satisfied.
- Assuming the CoS guarantees approval — it establishes sponsorship but doesn't determine the whole application.
- Ignoring occupation-specific requirements — ATAS or a criminal record certificate can apply to particular applications.
- Providing inconsistent information — the form, CoS and evidence should describe the same employment and circumstances.
Frequently asked questions
Do I need a job offer before applying? +
The Skilled Worker route requires sponsorship for a specific eligible job by a licensed sponsor. A valid Certificate of Sponsorship is required as part of the application.
When should I apply after receiving my CoS? +
Your CoS must normally have been assigned no more than 3 months before the date of application.
Can I apply for a Skilled Worker visa from inside the UK? +
Yes, where you meet the requirements for an in-country application and are not in a category from which switching is prohibited.
Can I switch from a Visitor visa? +
No. A person who has or was last granted permission as a Visitor cannot switch into the Skilled Worker route from within the UK.
Can I switch from a Student visa? +
Potentially, but specific course-completion or timing requirements apply.
Do I need to pay the Immigration Health Surcharge? +
Most Skilled Worker applicants must pay the applicable IHS. Qualifying Health and Care Visa applicants are exempt.
Do I need a tuberculosis certificate? +
It can be required in relevant entry-clearance cases. Whether you need one should be checked against the applicable tuberculosis rules.
Does every Skilled Worker applicant need a criminal record certificate? +
No. The requirement applies where relevant under the Skilled Worker rules.
Can UKVI ask me for more documents after I apply? +
Yes. The caseworker guidance provides for requests for further information and document verification where necessary.
Is receiving a CoS the same as receiving a visa? +
No. A CoS is sponsorship for the proposed job. UKVI still decides whether you meet the full Skilled Worker requirements.
