You could attempt to take the NCLEX-PN instead and in California, LVN's fall under a separate board from the RN's. You may download the application from the website but you should contact the BVN directly for specific questions regarding your case. Their website is: BVNPT - Vocational Nurse Licensure Application Forms
The Board of Registered Nursing has been particularly scrutinizing of clinical rotations from graduates of Philippine nursing programs
with the claim that the OR, L&D, and nursery rotations were not held concurrently with lectures. Some were told that their Psychiatric Nursing rotations did not meet California's requirement. I don't think it's necessarily the fact that you failed the NCLEX-RN twice in the past. The current pool of IEN applicants in California are ones who already have a US SSN, many of whom are previous test takers who weren't quite successful on their first attempt.
Should you decide to take the NCLEX-RN in another state (which is definitely an option in your case), be prepared to make that state your home because you will still have a hard time endorsing an out of state RN license to California given that they already determined that you didn't meet their requirements for licensure.
