I am looking to get my 3A in New York State. I held my core/RT in Indiana for over a year and from what I've read on the NY state website is that I have to show proof of at least a year. I have tried to find out how to get my old info from Indiana, but I keep hitting brick walls. I do not have my card or my old number. I held my core 06-08 I believe. Any help would be appreciated.
