Dear, I am Pakistani citizen working in ministry of health, Maldives. I have to go to Peru embassy & sign some documents. Here in Maldives no Peru embassy, therefore i have to go to Peru embassy, china. I took appointment Peru embassy china to appear & sign. In Maldives, i applied for visit visa in china embassy for 2 day to go to Peru embassy, china.I showed email of Peru embassy china but they refused to give me visa , replied take visa from Pakistan. I showed my resident card of Maldives but sorry visa not issued & my whole appointment waste.Is it necessary for resident to take visa for home land country or can take visa of resident country???
