if you end up taking your PE in a state different than the FE state, with your application you have to have the FE state send documentation that you passed to the PE state.
I'm from California and I took the FE exam in Illinois. My results were not sent to Califonia's Board of PE.
I had to send in a small fee along with a written request to the Illinois Dept. of Professional Regulation and ask them to certify my scores and send a verification form to the California Board of PE. I also have to complete another NCEES application, print it and mail it along with a fee to the California Board of PE.
If all goes well I should be receiving my California EIT certificate in about 2 weeks.
