关于修改IC地址Am I required to update my change of address? Yes. You must report your change of address no later than 28 days from the date of change of residence. If you fail to report a change of address within the stipulated time frame, you are guilty of an offence and shall be liable on conviction to a fine not exceeding S$5000 or imprisonment for a term not exceeding 5 years or both. 现在修改地址需要有文件证明新地址的有效性，亦即需要携带一些Documentary evidence,如近期账单、银行文件之类，带上相关证件直接去邻里警局是最便捷的方式。 详情请参考ica的说明 http://www.ica.gov.sg/page.aspx?pageid=141&secid=72#procedure
