龍門任擺，前文講到香港入境處有機會不承認港人在英國所生的子女擁有中國國籍，因此不會發出特區護照，帖文連結如下：

英國國籍法實行 jus soli with restrictions，即是在英國出生，不一定自動成為英國公民，除非父母其中一方是英國公民或已取得無限期居留indefinite leave to remain (ILR)。

雖然根據英國內政部資料，父或母其中一方是：

1. right to re-admission

2. right of abode

3. permanent residence status, if you were born on or before 30 June 2021

4. settled status under the EU Settlement Scheme

在英國出生的子女都會自動成為英國公民，但 1 和 2 是指父或母是來自英聯邦國家，香港不屬於英聯邦，而 3 和 4 是指父或母是 EU 或 EEA 公民。

因此，以 BNO Visa 移民英國的港人，在未成為英國公民或取得 ILR 前，所生的子女不能自動成為英國公民，假設子女不能加入中國籍取得特區護照，就須要按照 Hong Kong (British Nationality) Act 1986 6(2) 取得英國海外公民 British Overseas Citizen (BOC) 身份。

(2) Where a person born on or after 1st July 1997 would, but for this paragraph, be born stateless, then, if at the time of the birth his father or mother is a British National (Overseas) or a British Overseas citizen by virtue of paragraph (1) above, he shall be a British Overseas citizen.

根據 2017 年英國高院案例 MK (A Child By Her Litigation Friend CAE), R (On the Application Of) v SSHD [2017]：

…those who do not automatically acquire the nationality by operation of their own national law but to whom it is open to acquire such nationality by registration or a similar process should they chose to do so.

即是，如果香港入境處在子女出生後一年內都唔批護照，子女會變成無國籍人士，之後就可按照 HK Act 1986 取得 BOC。

注意，開頭提到現時只要父母有 BNO，沒有 BNO 的子女都可以申請 BNO Visa 移民英國，但這些子女本身不是 BNO 或 BOC，若他們在英國「搞出人命」，就無法動用 Hong Kong (British Nationality) Act 1986 6(2)，在英國所生的子女無法成為 BOC，若香港入境處不發出護照，就會真正成為無國籍人士 stateless person。

根據英國國籍法 British Nationality Act 1981 Schedule 2：

Where a person born in the United Kingdom after commencement would, but for this paragraph, be born stateless, then, subject to sub-paragraph (3)—

(a) if at the time of the birth his father or mother is a citizen or subject of a description mentioned in sub-paragraph (2), he shall be a citizen or subject of that description; and accordingly

(b) if he is born legitimate and at the time of the birth each of his parents is a citizen or subject of a different description so mentioned, he shall be a citizen or subject of the same description so mentioned as each of them is respectively at that time.

UK Gov https://www.legislation.gov.uk/ukpga/1981/61/schedule/2

簡單講，無國籍子女會 ’…subject of the same description…’，取得跟父母一樣的英國居留身份 ，即是 BNO Visa 身份，但問題是 BNO Visa 只是一個居留身份，不是國籍，子女會依然是無國籍，不能申請護照。

咁點算？又唔洗怕，在父母 5 + 1 後取得英國國籍，子女同時會獲得英國國籍。

另一個解決方法是，他們在未成為英國公民或取得 ILR 前，不要搞出人命。若想搞出人命，就需要搵個符合「資格」的 partner！

其實，英國本身有法例容許在英國或英國海外領土出生的無國籍人士成為英國公民，但都係要住夠五年先可以申請入籍：

You were born in the UK or a British overseas territory

You can apply if you:

• are under 22 years old

• have lived in the UK or a British overseas territory for at least 5 years before the date of your application

• were in the UK or a British overseas territory exactly 5 years before the Home Office receives your application

You should also have spent no more than 450 days outside the UK or British overseas territory during those 5 years.

If you’re under 18, you’ll have to show it’s not reasonable to expect you to get citizenship of another country, for example by your parents registering your birth at an embassy or high commission.

無國籍人士或因政治原因成為無國籍，在未成為英國公民前需要出國，可以申請 British Certificate of Travel，可參考呢個帖文：
