This is my first letter to write in this BB. I feel I may share with you some of my past experience.
I was a RN in Hong Kong, and due to the 1997, I migrated to USA and continue my nursing profession here.
CGFNS is required before you apply for RN Examination, known as "NCLEX" for the most states in USA except California,Florida, NewYork and one more, I could not remember. I think, probably there is center for CGFNS TEST CENTER in China, that I am not 100% sure. Hong Kong is one of the test center. Since the Commission for Graduates of Foreign Nursing School (CGFNS) tries to compare the educational/ clinical requirement for NCLEX in USA standard with the foreign nursing schools before you are allowed to take the test. I took the test,CGFNS, in Hong Kong in 1991 and passed, before I took my NCLEX in Los Angles.
The Test includes the Mutiple Choices Questions in Medical, Surgical, Pediatric, Psychiatric and Obsterical Nursing plus Test of English (TOEFL) , and required to pass at least 500 in score before a certificate issued to you.
Some hospitals may hire those foreign nurses with Certificate of CGFNS, as it is believed close to NCLEX, while waiting for the NCLEX.
Things changed a bit now. If you are in the states I mentioned above, you may just take the NCLEX directly without the CGFNS, but not the other states and still require you to take CGFNS first.
Nowaday, thanks to the internet technology, information search is much easier. By the way, I believe the pay in USA for nurses is the best, and you can immgrate to USA based on RN qualification, almost 99%.
Good luck to you, and if I could answer your questions, please reply, and I try to answer.
