Partner is a British Citizen/ILR/Refugee
Are you in a relationship with someone who is settled in the UK?
The Immigration Rules allow for applications from people who are in a relationship with a ‘settled’ person – that is, where your partner is British, has Indefinite Leave, or has been granted Refugee Leave. You have to show, however, that there are “insurmountable obstacles” as to why your relationship cannot continue overseas, and why you should, therefore, be allowed to remain in the UK.
An insurmountable obstacle is described in the Immigration Rules as a very significant difficulty which could not be overcome, and which would cause very serious hardship for you or your partner. This is a very high standard and before you consider making an application on the basis of your relationship with a settled person, you need to have very strong reasons as to why your relationship cannot survive anywhere but in the UK
