Indefinite Leave to Remain
Indefinite leave to remain is the granting of Permanent Residence in the UK. Once it has been granted, there are no longer any immigration related restrictions on the work or business you may do in the UK, and no time limits on your stay in the UK.
You should note that to keep your permanent residence you should not spend longer than two years outside the UK. You should maintain ties to the UK and should consider the UK as your home(Permanent Residence). If you continue to only spend short periods of time in the UK over many years it is likely that there will come a time when you will lose your indefinite leave to remain in the UK.
