Visit For Medical Reasons

You should check the basic eligibility requirement for a Standard Visitor visa and meet any additional requirements or provide additional documentation to prove your eligibility. The requirements also vary for the purpose of your medical visit. For instance, if you are visiting as an organ donor, you can
• only visit to donate an organ to a family member who you are genetically related to (for example your sibling or parent) or
• someone you have a close personal relationship with (for example your partner or friend).
You also need to provide a letter from the lead nurse of the transplant team, a General Medical Council registered specialist or a registered NHS consultant that confirms:
• you are a donor match to the recipient, or
• you are being tested to see if you are a potential donor,
• the recipient is genetically related to you, or in a close personal relationship with you and
• when and where the transplant or tests will take place. The letter should be dated no more than 3 months before you intend to arrive in the UK.
You must prove that the person you’re donating an organ to is legally allowed to be in the UK. If the recipient is not legally resident in the UK, you must provide their name, nationality and date of birth in your application.
All visits lasting longer than 6 months require a Standard Visitor visa regardless of your nationality. You can either apply for a Standard Visitor visa before you travel to the UK that lasts for up to 12 months and costs £190 or visit for up to 6 months and apply to stay longer when you’re in the UK for a fee of £993 (you can stay up to 12 months in total).
Depending on where you come from, you may also need a certificate that proves you do not have tuberculosis (TB).
