Thanks so much for a scan of the letter. Nice to see it all in writing.
Personally, I'm surprised that they want photocopies of supporting documents now instead of originals. I guess any suspicions of tampering could be sorted out with contact to the issuing institution, and I guess it would address the occasional problem of applicants not getting all their originals back. Plus, if Sheffield is only getting scans of documents anyway, it's not like they would have the original document to hand to inspect themselves. Maybe there was a bit of me thinking the staff at the NY scanning hub would have been trained to detect potential document alterations before scanning them.
But regardless, thanks again for providing this.
Solid evidence.
