In some countries "short" birth certificate includes all information INZ wants, i.e. it includes name and surname of parents. This is my case. I asked INZ whether they'd accept "short"/"simple" birth certificate if info they want to see is there. Response I got on the phone: should be enough, but if case officer wants to see the document titled "full" birth certificate, they may ask for it... My document is titled "Extract from birth certificate" (full version would contain any changes, such as change of surname etc-not applicable to me). Obviously, it's expensive and takes time so I'd rather go with the certificate I have. Anyone with actual experience? Thanks!
