Unfortunately, even if you are very ill, normally just telling the Judge about your condition is not enough. You must have medical evidence which shows you are unable to leave the UK on a normal day. This is different to saying you will not be able to get help from a doctor outside the UK.
‘Medical evidence’ means a letter or this Home Office form written by a medical professional (for example your GP, consultant or hospital doctor).
Tips: The medical evidence must explain why you cannot leave the UK. Your doctor should explain:
1. why you cannot travel, even if you have medication and a medically trained person ('medical escort') travelling with you
2. what problems you may have on the journey
3. how often you have appointments with your doctor, and when they last saw you.
