Evidence That Your Sponsor is Not in Breach of UK Immigration Laws
If you intend to visit the UK under a work sponsorship or are being sponsored by a friend, family member, or spouse, it’s important to have a good understanding of immigration rules and laws.
Sponsors who do not comply with Home Office rules may be deported or have their sponsorship license downgraded or revoked. If you need help with your sponsorship application or are looking for guidance on whether your sponsor is in breach of immigration laws, call us at London Immigration Lawyers today on 0204 502 8582 or contact us online.
What is Evidence That Your Sponsor is Not in Breach of UK Immigration Laws?
A sponsor must prove they are legally in the UK by providing the following information and documentation. Visa evidence that your sponsor is not in breach of immigration laws may include:
- A valid Sponsor License
- A valid UK visa or British passport or evidence of their immigration status.
- Their biometric data, such as a Biometric Residence Permit
- A clean record on their Sponsor Management System (SMS)
- Documents proving the relationship between the sponsor and the person being sponsored
- No previous breaches, which can be proven through application form checks, HM Revenue and Customs and the Department for Work and Pensions.
Sponsors are in a key position of trust and help verify the legitimacy of people entering the UK. Therefore, they mustn’t be found to be abusing the system or not following UK immigration laws.
If immigration services have reason to believe your sponsor has breached immigration rules and their duties as a sponsor, you could lose your right to stay in the UK and subsequently be deported if you do not obtain a different visa or sponsor to remain in the UK. They could also face legal consequences.
What Documents Are Needed When You Have a Sponsor for a UK Visa?
To be able to live or work in the UK under a sponsor, your sponsor must provide documents to the Home Office to support your application and show evidence of funds accessible to applicant.
Some of the documentation required by the Home Office when you have a sponsor for a UK visa may include the following:
- Certificate of Sponsorship (COS)
- Completed COS application completed by your sponsor
- Your sponsorship letter (also known as an invitation letter)
- Employment contract with proof of salary, role, start and end dates, and working hours
- Details of employment, including job title, salary, and occupation code or reasons why you are travelling to the UK.
- If undertaking academic research, they must provide a letter confirming the arrangements for your research or exchange or outlining your research.
- Document evidence of the relationship between sponsor and applicant (if you have a personal relationship with your sponsor). Proof of relationship for visa application includes a marriage or civil partnership certificate.
- If they plan to support the applicant financially, they should provide proof of sufficient funds through bank statements and other forms of proof.
- A receipt confirming the sponsor has paid a fee for assigning the COS
- If the person sponsoring you is someone you were previously married to and are now separated from, you must have proof of continued relationship during separation.
