Xbox, I am not sure on what condition her friend got work permit. If she had applied before the retrogression happened to nurses (which happened only last year as compared to other EB3). 

Could anyone explain how those RNs got recent work permit?

Many State Board of Nursing accepting CES from CGFNS is a good sign (though CA and few other states make ISc Nursing from Nepal deficient in Psychology courses and require about 3 credit hours remedial classes). Colorado and New Mexico accept both TU and CTEVT graduates from Nepal without any remedial classes.

Thanks
