This situation might be odd but I just received a letter from visa office in which one of the documents requested is unmarried certificate. In the past ten years I have been in China, US and currently in Canada. I am very confused how am I supposed to proved the fact that I have never been married.... If any of you have had this experience, could you input some information where can I get this damn document.? Would a notary from a Canadian lawyer suffice? or I have to get certificates from all three countries?
