PR Renewal所需文件有谁的PR到期了去renew过吗？听说需要以下3份文件： (i) A letter (issued not more than one month ago) from the employer addressed to the Controller of Immigration, stating the date of employment, position held & monthly salary; (ii) A statement from the CPF Board showing the CPF Contribution History for the last 12 months; and (iii) Income Tax Notices of Assessment for the last 3 years. 这(i)应该可以在公司搞定，不懂(ii)和(iii)应该怎样，(ii)是要到CPF那边去让他们给开个证明吗还是在哪里可以自己打印？(iii)呢？是不是需要去趟IRAS?烦请申请过的指点一下，谢过先
