Hi Nazib

a good photocopy certified as a true copy of the original by a lawyer is acceptable. Please check the requirements for lawyers who fall under the category of people who can certify documents. I'm not sure if there are different grades of lawyers who can certify documents.

Another way will be to scan the photocopy you have if that's a good copy and apply online, if the visa type you are applying for can be applied online....

Hope this helps. And good luck
