The short answer is if you want to get your CA license quickly, have everything in hand (transcript, application, photos, live scan, etc.) and personally deliver it to BRN in Sacramento (yes, it's costly, especially for people who live out of state, but I guarentee you this is the fastest way if you want to be 100% sure that they receive all the necessary documents).
However, I didn't do that and this is what happened to me:
1/12/18, applied online, mailed my fingerprint card, and request all my schools (4 schools total) to send my official transcripts to BRN.
3/12/18 saw my temporary license posted on BreEze (here is where I made the mistake of innocently believing I just needed to wait for a couple more weeks for the permenent one)
3/19/18 got a letter from BRN saying "need transcript reflecting completion of coursework in x, y, and z.
I ignored the letter because I know all my schools mail my transcripts to them.
I was finishing my DNP degree, selling the house, packing, trying to make a cross country move to CA, in short, lots of going on, didn't have the time to look into this matter.
Fast forward, I moved to CA, checked BreEze again in July, the same message.
8/2/18 drove to Sacramento, went to BRN in person, waited for an hour in line. Kimberly at the front desk told me that they never received any of my transcripts (that's $40 down the drain). I asked her what's the most secure way to get my transcripts to them. She told me to bring them in person. (However, if you graduate from a foreign nursing school, you cannot bring your official, sealed transcript in person. It has to be mailed or emailed by your school)
I went home, requested from all four schools again. This time, I asked them to mail the official transcripts to me.
8/13/18, second attempt to go to BRN in person. Waited for 2 hours this time (it was Monday). A different lady came out and took my transcripts. She asked me to wait while she went back to check on my file. 20-25 minutes later, she came back and told me I still don't meet the psychology requirement but what I can do is to have my school email her supervisor and say that psychology was incorporated into my BSN curriculum. I tried to contact my school then, but wasn't able to get a hold of anyone. So I drove all the way back home (2.5 hours)
8/14/18 finally got a hold of someone from my school who was willing to provide the letter (apparently they do this a lot for nurses who move to CA)
8/16/18 saw on BreEze that my permanent license was posted.
So overall it took me 7 months. It didn't have to if BRN didn't lose my transcripts or communicate to me clearly that they didn't receive my transcript. Apparently all the mails that get to send to BRN actually go to the state mail room, then they get sorted. This means the transcripts can be mixed with mails that go to any other state agencies and there are a lot of them. When I was there both times, there were plenty of people who went there because their transcripts were never received by BRN. I know it's partially my fault because I didn't have the time to chase after BRN because I had other things to worry about in my life.
