As long as he signs it, yeah you can mail it in.
i am currently overseas and my professor has written my letter.
hes asking me if he can just send it to me by PDF so that I can send it.
is it possible that I could just fax it or mail it myself along with the form?
is this allowed in some way possible?
If he MAILS it in, the professor's signature has to be across the seal of the envelope flap.
So it is better he get the pdf and fax it in.
Or have the professor seal it with the cover sheet from LSAC inside, sign the seal, and send it to him INSIDE a bigger envelope.
I think the email is best so he has extra copies if he wants to apply for scholarships and such.
