Not rumors at all, all harsh realities for many foreign educated grads and nurses, as many are not meeting CA BON minimum requirements that have been on the books as written policies since 1987.
CA BON is cracking down hard on many applicants. You have to basically be able to pass CA's requirements, even if you're trying to endorse any out-of-state RN license. You have submit your college transcripts and there stands a very high chance, it will be denied.
Depending on which country you got your degree from, it ranges from not having taken the clinicals and the theory section in the same semester, not months or years later (concurrency issues) or lacking in certain courses or lacking sufficient hours. It doesn't matter if you have 1,000's of hours of experience, it will always fall back to your original education.
This affects just about every country, even those from the UK, Russia, Phillipines, China, India, etc. With the high unemployment of new grads and even experienced nurses in CA alone, I don't think you find CA BON budging off their recent enforcements of the various 25 year old rules.
You do have the option of making up those deficient courses, but realize you'll be competing with already enrolled students on a very limited open slots for foreign students, with an excepted time frame of about 18-24 months or longer to complete those.
You could ask this same question in the "World Nursing" forum and under the "Nurse Registration" section, just take a peek over there, you'll see plenty of foreign students all caught up in this scenario. Sad, but true.
