Good preparation prevents delays. This chapter shows you what to collect, when to do it, and how to keep everything consistent with your Certificate of Sponsorship (CoS).
Before you start
A little alignment with your employer saves a lot of rework later.
- Confirm your employer holds a sponsor licence and will issue a CoS for the correct occupation code.
- Agree a realistic start date that leaves time for documents, appointments, and decision.
- Clarify whether the employer covers any costs (fees, IHS, priority, relocation).
Documents — what you’ll likely need
Think of this as your core pack. You may not need every item in every case, but having them ready speeds things up.
- Passport (and scans of any recent passports if available).
- English proof if required for your route (approved test result or ECCTIS degree confirmation).
- Tuberculosis (TB) test certificate if your nationality/country of application requires it.
- Degree certificate and ECCTIS letter (only if using degree-based English proof).
- CoS details once assigned (number, occupation code, salary, hours, work location, start date).
- Travel history notes (entry/exit dates for the last 10 years can be handy).
- Police/clearance: usually not needed for Skilled Worker, but keep any criminal record checks you already have organised.
- Translations for any non-English documents (see translation tips below).
Keep names, dates, and numbers identical everywhere: passport, CoS, application, English test/ECCTIS letters.
Where to get (and how to prepare) each item
Setting aside time for sourcing and formatting avoids last-minute scrambles.
- English test: book an approved test type that your route accepts. Test centres can fill up—book early.
- ECCTIS: if relying on your degree, start this early; processing varies and you’ll need scans of your certificate/transcripts.
- TB test: only from approved clinics for visa purposes in eligible countries; check the validity window.
- Translations: use a translator who can provide the required certification statement; keep translator contact details on the certificate.
- CoS: ask HR for a printout or PDF of the CoS info (even a screenshot) so you can cross-check your application entries.
Timing — build a simple, realistic schedule
You don’t control every step, so build a buffer around these pinch points.
- CoS assignment → you can only finalise once you have your CoS details.
- Identity step → biometrics appointment slots (outside the UK) or ID Check app (if eligible). Busy seasons book up.
- Service levels → Standard vs Priority/Super Priority availability varies by country and time of year.
- Travel → don’t buy non-refundable tickets until you have a decision.
Digital hygiene — how to package your files
Caseworkers need to read your documents quickly. Help them help you.
- Use clear scans (no glare/cropped edges). Combine multi-page PDFs.
- Name files descriptively:
passport.pdf,english-ielts-ukvi.pdf,tb-certificate.pdf,cos-summary.pdf. - Keep file sizes within upload limits; export to PDF instead of photos where possible.
- Store everything in a single folder you can re-use for extensions and ILR.
Avoiding common blockers
A few pitfalls trip people up again and again—easy to dodge if you know them.
- Wrong test type / expired results → book the approved English test; check validity.
- Occupation code mismatch → duties should match the chosen code; titles alone aren’t enough.
- Salary counting extras → thresholds usually rely on base salary, not allowances/bonuses.
- Inconsistent details → copy the CoS exactly (names, dates, hours, locations).
- No TB from an approved clinic → only official clinics are accepted where required.
- Untranslated documents → provide certified translations for anything not in English.
Dependants — prepare in parallel (if applicable)
If your partner/children will apply with you, start their documents early.
- Relationship proof: marriage/partnership certificate, or cohabitation evidence if applicable.
- Children: birth certificates; consent letters where required.
- Maintenance: some routes require funds for each dependant unless your sponsor certifies support.
After you submit (what to expect next)
Knowing the next steps keeps stress down.
- Fees and (for many work routes) IHS are paid online when you submit.
- Identity: biometrics at a centre or the UK Immigration ID Check app.
- Decision: you’ll get an email; your passport will be returned (if taken) or your eVisa will reflect your status.
- Travel & onboarding: coordinate with your employer once you have the outcome.

FAQs
Do I need to wait for the CoS before filling the form?
You can draft parts of the form, but you’ll need the CoS number and exact details to submit. Avoid guessing—mismatches cause delays.
Is a police certificate required for Skilled Worker?
Usually no, but you must declare any criminal history honestly. If you already have clearances (for work), keep them tidy—some employers ask for them separately.
My English test is expiring soon—what should I do?
Book an approved test as early as possible or consider ECCTIS degree confirmation if eligible. Make sure your result will still be valid by the time you submit.
Which documents need translating?
Anything not in English (or Welsh) typically needs a certified translation with the translator’s confirmation, date, and contact details. Submit both the original and the translation.
Can I travel while my in-country application is pending?
Usually not advisable—leaving the UK (or the Common Travel Area) can be treated as withdrawing the application. If travel is unavoidable, check the current rules for your route and seek advice first.
