可唔可以仔女係香港岀世,但係照拎到回鄉証同bc?
Having your cake and eat it? Well you can do the following -
The children being born in Hong Kong, so they will have Chinese nationality.
Move the whole family to the UK under the spouse visa / dependent visa system and then have the children register as a British Citizen at the same time as the non British Citizen spouse applying for naturalisation.
Please note that UK immigration law can change at any time and any changes will only make immigration to the UK harder not easier.
