Den dobge, Marta! I am a pharmacist from Russia. I am going to send my papers to Board of Pharmacy too. First important paper wich you need - the proof from your mother's country pharmaceutical institut that you graduated. It has to say that you was a student from ... year to... year.... It has to say what course or subject did you attend and how many hours. The letter has to be singed, stamped and sealed than an envelop. U need 3 envelops from your college. Start with a letter from your college. I already have it all and going to send to a Board. I know that it will take a whale for them to check all my papers. I know that a Bord will call to my college to be sure that that the letter is true. And the same for every paper. It takes time, unfortunately.
Good luck
