I have several original documents which I need to scan and copy, but need the date to be different from the original.
We are in the process of applying for migration visas, I had to do a skills assessment first which involved loads of time sorting old employment references and other related paperwork. The second stage is the visa application which requires all the same references but dated within a month of sending them. To save the hassle of going round and getting them sent out with a different date, I want to alter them myself.
Can it be done? Any help would be much appreciated.

Cheers, Gez
