I am an RN in Boston, MA. I just sent my ppwk down with the application filled out to the letter, a copy of the Nursys verification, copy of the medication error CEU and 2 copies of the fingerprints along with the $223 fee, sent is certified. It was received on Dec 7th and on Dec 17th the board had my license number posted. I still don't have anything by mail but that seemed pretty quick.
There is also an option to fill out the application online pay online and mail in the fingerprints.
