NCLEX-RN in California about to expire

Hi. I am a nurse from the Philippines who already passed the IELTS, the CGFNS and the NCLEX (California State Board of Nursing). I am being petitioned by an employer in California and has been waiting for the packet 4 (under EB3) for almost two years now. I took up the NCLEX in 2006. The California State Board of Nursing is requiring me to have a social security number first before being issued a license. Since the retrogression is still on-going (my priority date is August 2006) and it's impossible for me to have a social security number now that I am still here in my country, I am afraid that my nclex would reach it's expiration date which is three years from the date the result was released. Is there any way I can prevent this from happening? I cannot imagine myself taking the nclex again really. I do not want to go through with that again please .
