According to an email from the Sikh Coalition:

As a result of overwhelming activism by Sikhs and non-Sikhs worldwide, the Florida Department of Corrections will allow Satnam Singh to serve his sentence in Vermont, where he will able to maintain uncut hair....

Background on the case:

Singh, a forger, is scheduled to enter a Florida prison next week, and the state penal code is unrelenting on the point that incoming male prisoners must receive short haircuts and close shaves, no matter what their religious beliefs.

So grave a matter is a haircut that Singh's 84-year-old father said, "Please cut off my son's head instead of cutting his hair!" [Link]
