请问如果父母有一方是新加坡籍，在新加坡出生的孩子还有机会拿本中国护照吗？

母亲是新籍，貌似孩子可以选国籍但是父亲是新籍，孩子一定是新加坡国籍，除非在美国这种地方出生，拿美国护照但是父亲是新籍，孩子一定是新加坡国籍，除非在美国这种地方出生，拿美国护照

不是的我是新加坡籍，我女儿在新加坡出生，老公中国籍。女儿出生纸上直接写，孩子为新加坡籍。没有选择余地。除非孩子在中国出生，才有的选。我是新加坡籍，我女儿在新加坡出生，老公中国籍。女儿出生纸上直接写，孩子为新加坡籍。没有选择余地。除非孩子在中国出生，才有的选。

稍微查了一下两国法律中国的国籍法：
第五条　父母双方或一方为中国公民，本人出生在外国，具有中国国籍；但父母双方或一方为中国公民并定居在外国，本人出生时即具有外国国籍的，不具有中国国籍。
新加坡的宪法：
Citizenship by birth
121.
—(1) Subject to this Article, every person born in Singapore after 16th September 1963 shall be a citizen of Singapore by birth.
(2) A person shall not be a citizen of Singapore by virtue of clause (1) if at the time of his birth —
(c) neither of his parents was a citizen of Singapore.
另外有一条很有趣的：
134.
—(1) The Government may, by order, deprive a citizen of Singapore of his citizenship if the Government is satisfied that —
(a)
he has, while of or over the age of 18 years, at any time after 6th April 1960 acquired by registration, naturalisation or other voluntary and formal act (other than marriage) the citizenship of any country outside Singapore or having so acquired such citizenship before the age of 18 years continues to retain it after that age;

简单的答案就是：
公民+中国籍PR: 新加坡国籍，因为中国不给你中国国籍了
公民+中国籍非PR : 新加坡方面在18岁之前是允许双国籍的，18岁之后必须做一个选择，放弃其中之一。但是因为中国国籍法不允许双国籍，理论上你去中国领事馆注册中国国籍的时候会要求小孩放弃新加坡国籍。所以最后只能是中国国籍。

这里不讨论中国政府不正常执行法律的问题。

只要父母一方为新加坡国籍，在新加坡出生的孩子就自动是新加坡公民除非父亲是外国外交官，以及其他几种一般人遇到的情况除非父亲是外国外交官，以及其他几种一般人遇到的情况

134条是有限定条件的acquired by registration, naturalisation or other voluntary,要是父母有一方是坡籍,在新加坡生的孩子是citizen by birth的,不符合134条的限定,而且这个说的是政府剥夺国籍,不是个人renounce国籍acquired by registration, naturalisation or other voluntary,要是父母有一方是坡籍,在新加坡生的孩子是citizen by birth的,不符合134条的限定,而且这个说的是政府剥夺国籍,不是个人renounce国籍

楼主问的问题本来就是一方新加坡人， 一方中国人另外，剥夺国籍是新加坡国籍，而且是18岁以后，人家现在问的是新生儿另外，剥夺国籍是新加坡国籍，而且是18岁以后，人家现在问的是新生儿

我也没有说是renounce。我说的是放弃放弃既可以是主动的renounce, 也可以是被动的deprive。
或者说，只能保留一个比较妥当。放弃既可以是主动的renounce, 也可以是被动的deprive。

不是说18岁之前可以拿俩本护照吗？如何操作？

不在新加坡生先拿中国护照,再拿新加坡护照先拿中国护照,再拿新加坡护照

如果在新加坡生就不行了吗？

无法操作新加坡出生，大使馆要你出具非新加坡籍本地证明，新加坡不会给你这个证明，自动新加坡籍by birth。所以只能回国生新加坡出生，大使馆要你出具非新加坡籍本地证明，新加坡不会给你这个证明，自动新加坡籍by birth。所以只能回国生

应该不行吧父母一方是公民的话,宝宝自动认定是公民,citizenship by birth, birth certificate 上会写的。去中国大使馆给新生儿办护照,如果父母中一方不是中国公民,宝宝要证明没有加入其他国籍才给办护照。父母一方是公民的话,宝宝自动认定是公民,citizenship by birth, birth certificate 上会写的。去中国大使馆给新生儿办护照,如果父母中一方不是中国公民,宝宝要证明没有加入其他国籍才给办护照。

说的就是134条对楼主的问题不适用renounce 的话得21，男的必须服完兵役才可以renounce 的话得21，男的必须服完兵役才可以

嗯。服兵役的问题取决于16岁收到征兵令之前是不是已经放弃新加坡国籍，越扯越远了，楼主知道她的问题就好了。服兵役的问题取决于16岁收到征兵令之前是不是已经放弃新加坡国籍，越扯越远了，楼主知道她的问题就好了。

国籍可以自动放弃么？还是需要政府批准？

需要注册，政府有权力不批， 和楼上上的答案有关宪法： Renunciation of citizenship
128.—(1) Any citizen of Singapore of or over the age of 21 years and of sound mind who is also or is about to become a citizen of another country may renounce his citizenship of Singapore by declaration registered by the Government, and shall upon such registration cease to be a citizen of Singapore.
(2) The Government may withhold the registration of a declaration under this Article —
(a)
if the declaration is made during any war in which Singapore is engaged; or
(b)
if the declaration is made by a person subject to the Enlistment Act (Cap. 93) unless he has —
(i)
discharged his liability for full-time service under section 12 of that Act;
(ii)
rendered at least 3 years of operationally ready national service under section 13 of that Act in lieu of such full-time service; or
(iii)
complied with such conditions as may be determined by the Government.
(3) This Article applies to a woman under the age of 21 years who has been married as it applies to a person of or over that age.宪法： Renunciation of citizenship

政府应该会等服役完后批准
