小孩在英国出生，能加入英国国籍嘛？

夫妻有一方有英国籍（绿卡）孩子就可以入，详情问移民局大使馆那些吧

如果孩子的父母有永居或者英国国籍，那么孩子一出生就可以登记英国国籍。
如果不是的话，孩子也可以申请
Section 3(1) applications - children born in the United Kingdom to parents who are not settled in the United Kingdom and are not British citizens
Registration in this category will be at our discretion, if we believe it is reasonable under the circumstances and will be under section 3(1) of the British Nationality Act 1981. There are no formal requirements the child needs to meet providing they are under 18 at the time of application and are of good character if they are over 10 years of age. The application should be accompanied by as much evidence as possible to show us why the child should be registered as a British citizen.
