Most of the US graduate programs I'm applying to require official transcripts sent in a sealed envelope from the issuing university itself and not by the candidate. I visited my registrar office and they are willing to provide sealed envelopes containing official transcripts to me but they do not post these envelopes on their own. Will the US universities accept the envelope sent by the candidate instead by the university address?

I have written to the concerned office/graduate officer in the universities, but I think due to Thanksgiving, I have not yet received a response. Also they get thousands of emails so I’m not sure how soon I will get a response from them.

And timing is crucial because my university is in different state altogether which is a day’s journey from my place by train. And Indian universities don’t do well with telephonic or email support, so things have to be tackled in person. Apart from the cost issues.
