Here in the U.S., I have never been asked to show any of my degrees. Perhaps because it is verifiable by other means, I am not sure, but employers generally don't ask for proof that you do indeed possess a high school diploma, a B.A., an M.A., or a Ph.D.
In fact, when my husband was getting ready to come to the U.S. on a fiance visa, he asked me if he should translate or notarize his degrees. I told him that no one was going to ask to see them. No one has.
In Chile, though, you are often asked to provide copies of your degree. There was a job I considered applying for a few months ago, but they wanted a photocopy of any degrees I had, and I hadn't even received my Ph.D. degree in the mail yet. This would not have even been an issue applying for the same type of position here in the States.
To use my degree in Chile, I have had to take it through a strange process of authentication. I ordered an extra copy of both my M.A. and Ph.D from my university that was notarized by a university official, confirming its authenticity (I didn't want a stamp on the back of my only copy).
I then had to take it to the Texas Secretary of State where they issued a letter, stapled to each degree, stating that the notary public who notarized my degree is indeed authorized to notarize and that if she said it is a real degree then it is.
Now I have to take it to the Chilean consulate where they will legalize it for use in Chile. They essentially will issue some letter saying that if the Secretary of State recognizes the official who notarized my degrees, then they are indeed authentic.
Now I have to make sure they won't ask for my transcripts too...
Isn't beaurocracy a blast
I now leave you with G's mad/happy face:
