Here's what I did, hope this helps! (My uni does not send documents to other institutes and just hands over the sealed envelope to applicants for them to mail)
- Apply to your university for the transcripts, clearly mention to them that you need this for Visa purpose. Unis are used to this requirement and often have a separate cell for dealing with transcript requests.
- Typically, the transcripts come attested by default by the relevant authority from your uni: you just have to ensure that they put your transcript in a uni envelope, seal it, and finally stamp and sign the sealed back-flap. Do not tamper with the seal under any circumstances, ensure that it's secure
- Complete your profile in WES and pay the fees. This gets you your reference number.
- On the top of the sealed envelope, neatly write the WES Reference # along with their address.
- Get a clear, colour photocopy of your degree certificate. I laminated mine, but I guess that's not necessary
- Take a larger envelope (large enough to comfortably fit the transcript envelope plus the degree certificate copy) and put in the above two items inside it.
- Once again, write out the reference # and address on the outer envelope too, seal securely and courier.
