How to Use Your CoS Number for Family Applications
Your Certificate of Sponsorship holds the key reference number for family visas. Partners and children link directly to this number during applications. Home Office processes these together for faster decisions under current rules. A-rated sponsors certify maintenance easing financial proof for dependants.
Grasp CoS Role in Family Visas
Main applicants receive a unique CoS reference upon assignment from their sponsoring employer. Partners enter this exact number in their dependant form section to ensure correct linking. Home Office matches applications instantly, ensuring linked processing within standard timelines for families. Correct entry avoids separate queues and potential refusals, streamlining the entire process. Families benefit significantly from unified decision letters post-submission, simplifying their immigration journey.
Sponsors record start dates precisely on the CoS, ensuring its validity for up to five years maximum. Dependants must apply within three months of this assignment date to avoid issues. Invalid links trigger rejections if the CoS withdraws before its intended use. An A-rated sponsor status allows maintenance certification, covering partners fully and simplifying financial requirements.
Financial thresholds apply unless your sponsor certifies maintenance on the CoS for dependants. Workers must show £1,270 in personal funds or provide sponsor endorsement. Partners add £285 maintenance proof if uncertified by the employer. Children require £315 for the first and £200 for each further child under Appendix Finance rules.
RQF6 Restriction Alert
From 22 July 2025, roles below RQF Level 6 bar dependants on the Skilled Worker route. Temporary Shortage List jobs prohibit family entirely until 31 December 2026.
Verify CoS Before Family Links
Sponsors assign CoS via SMS, confirming SOC 2020 codes and salary details exceeding the £41,700 general threshold from 2025 updates. Workers must check the reference validity, lasting three months from issuance, for dependant use. Home Office rejects applications if the CoS cancels or the sponsor downgrades to a B-rating post-assignment. Pre-verify A-rating status for maintenance certification benefits.
Partners gather marriage certificates or civil partnership proofs early in the application process. Children supply birth certificates, clearly linking parentage to the main applicant. Funds evidence follows if no sponsor certification appears on the CoS record. Applications sync via a shared reference, avoiding individual scrutiny delays.
Biometrics appointments align for the entire family post-link confirmation online. Processing typically takes three weeks for linked in-country switches eligible under current rules. Priority service adds fees but cuts waits to five working days reliably.
Out-of-country entries demand Defined CoS types, which sponsors must assign within 90 days of allocation.
Link Applications Step-by-Step
Access Your CoS Reference
Log into your sponsor's SMS account or receive an email with the 12-digit CoS number post-assignment. Confirm the start date does not exceed three months prior to dependant submission. Note the SOC code and salary, matching the £41,700 minimum or higher thresholds.
Prepare Dependant Documents
Collect relationship proofs like marriage certificates, translated if necessary. Gather funds evidence unless an A-rated sponsor certifies on the CoS. Ensure TB tests for applicants from listed countries remain valid for six months.
Enter CoS in Partner Form
Select the dependant route and input the main CoS reference exactly in the linking field. Upload supporting documents showing shared finances or accommodation plans. Pay fees, including the IHS at the £1,035 annual adult rate for 2026.
Submit and Track Together
File online simultaneously for priority linking benefits, if available. Monitor via your UKVI account for unified decisions, typically within eight weeks for standard service.
Maintenance Certification Details
A-rated sponsors declare maintenance on the CoS, covering workers and dependants fully under Appendix Finance. This waives the £1,270 personal funds proof for main applicants inside the UK for over one year. Partners avoid separate £285 showings with certification active. Health and Care visa roles demand extra NHS contract notes on CoS summaries.
B-rated sponsors force full funds evidence from all family members applying for their visas. Scholarship recipients must supply agency consent letters if they received an award within 12 months prior. CoS end dates cap at four years for new entrants, including prior Graduate route time.
Pre-registration nurses limit to eight months sponsorship with specific NMC confirmation clauses. Sponsors must halt support post-eight months without full registration achieved. Client contracts detailing on the CoS prevent third-party routine work violations. PAYE references confirm tax compliance, which is essential for all assignments.
Pre-Submission Checklist
- Valid CoS reference number active within three months
- Relationship documents like marriage or birth certificates
- Funds proof or sponsor A-rated certification confirmation
- TB test certificates if from high-risk countries
- English proficiency for partners if principal exempts
- IHS payments receipt for all dependants

Handle Common Linking Pitfalls
Mismatched CoS numbers cause instant mismatches in Home Office systems, leading to significant delays. Families often resubmit, wasting £490 partner fees plus Immigration Health Surcharge losses. Sponsors must update their SMS promptly if job details shift post-assignment. Track expiry dates rigorously, avoiding three-month lapses.
In-country switches demand prior non-visitor status for eligibility checks. Out-country Defined CoS lock salary fields, unchangeable except for points-equivalent hikes. Health and Care applicants must add criteria summaries in the job description fields, which is mandatory.

CoS Types for Family Support
Defined CoS suit out-country workers needing pre-allocation applications via the SMS. Undefined versions serve in-UK extensions without Defined mandates strictly. Sponsors avoid mixing types, risking licence revocations entirely under compliance rules. New entrants cap four years total across routes seamlessly.
Pre-assignment checks ensure workers meet genuine vacancy intents fully. Skilled Worker visa application timelines hinge on CoS validity periods observed. NMC clauses protect short-term nurse sponsorships, limited to eight months precisely. Agent details record transparently if recruitment intermediaries assist. ATAS certificates flag for sensitive tech roles additionally.

Post-Link Monitoring Tips
Home Office notifies via email if links process successfully together, providing peace of mind. Families track a single reference across all applicant accounts online for unified updates. Delays can hit eight weeks standard, but priority cuts to five days with additional £500 fees. Sponsors must report changes like absences within ten days, which is mandatory. Retain Appendix D records for audits lasting six years.
Refusals cite invalid CoS most frequently across dependant cases, highlighting the importance of accuracy. Successful links grant conditions matching the principal applicant, valid for up to five years. ILR paths open after five years of continuous sponsorship, provided all conditions remain unbroken.
