儿童的永居算吗？
Travelling outside the UK
You should take your BRP with you if you travel outside the UK otherwise you may be refused re-entry to the UK.
If you stay outside the UK, Ireland or the Crown Dependencies (Isle of Man, Guernsey and Jersey), for 2 or more years at a time your ILE or ILR will automatically end. If you have been granted settled status under the EU Settlement Scheme, your leave will automatically end if you stay outside the UK, Ireland or the Crown Dependencies (Isle of Man, Guernsey and Jersey) for 5 or more years.
If this happens you will need to apply for entry clearance as a returning resident before coming back to live in the UK. Further information is available in the guidance on returning residents visas.
