1. 如果不是紧急状况但是有计划要回国，尽量提前一个半到两个月左右申请。预约的时候最近一个多月的slot都已经满了
2. 所有材料都记得打印和复印一份，材料准备得越全越好
3. 带现金。签证中心也可以打印（只收现金），打印一块钱一张，复印5毛钱一张。
4. Walk in 早早去签证中心排队。最近办签证的人太多了，我因为紧急情况直接Walk in。在网上查的是9点开门，我们比9点稍稍早一点到，里面的队伍已经排满了。大概等待了两个小时才拿到queue number，全程站着排队，拿到queue number后又等了大概一个多小时办理。
Application Materials:
 a. Application form completed online (print-out of the full form);
 b. Original passport and copy of the information page;
 c. 1 photo; （这个我没有带，工作人员也没有找我要，填申请表的时候已经上传成功，打印出来的申请表也是有照片在上面）
 d. Certificate of lawful stay or residence permit in Singapore (for citizens of other countries who are in Singapore);
 e. Original Chinese passport or original Chinese visa (for those who had Chinese nationality and later joined a foreign nationality); （这个我也是没有，印象中我好像已经把护照交给中国大使馆了，不过有提供之前大使馆开的我已经surrender了我的中国护照的证明）

g. Materials for Q2 visas are as follows:
① Certification (marriage certificate, birth certificate, household register, certification of kinship issued by Public Security Bureau or notarized certification of kinship) showing the relationship of family members between applicant and inviting individual （我用的是出生证明）
② An invitation letter issued by a Chinese citizen or a foreign citizen with a Chinese permanent residence permit who lives in China （我使用的模板是直接在visaforchina找的，可惜贴不了链接，可以google搜索“邀请函模板Q2签证”）
③ Proof of the  inviting individual's Chinese identity (e.g. Chinese ID card, household register), or foreigner's passport and Chinese permanent residence permit
h. For emergency humanitarian visas other than those mentioned above, such as those for funerals or visits to critically ill relatives in China, the identity documents of the deceased or ill relative (e.g. foreigner's passport, etc.), a death certificate or a certificate of diagnosis, critical illness notice issued by a hospital, proof of kinship, etc. shall be submitted
这个情况可以申请特急，第二天拿到签证。需要准备病危通知书/死亡证明，以及家属关系证明
费用：Walk in会另外收取60新币。付款只可以用Paynow或Cash。
我是第一次申请中国签证，最多只能给半年两次，申请不了一年多次
