Nurse from Israel

Hey everyone!
This is my first post, so I hope that Im writing it at the right place!

I have a few questions and I really hope that I could get some help here, because I read a few posts and the responses seemed to be very practical and helpfull.
I'm a nurse from Israel. I have been planning for quite a long while already to move to the U.S and live in Oregon, because I love nature. I have an American B.A degree from University of New England. I'm 26 and have a 5 year experience as a nurse. So my questions are:

1. I heard that each state has different requirements for education and licensure examinations. What are the requirements in Oregon, NCLEX , CGFNS, both?

2.Will my nusing B.A degree be valid in Oregon, although I got it from other state?

3.I'm allergic to latex, are there any job opportunities for a person like me, currently I'm working in the community (vaccinations and developement examinations of children)

4. I've just found out on your site that many people have allergies in Oregon, as I had atopic dermatitis all my life, is there any chance to find a place to live in Oregon or a place with nature and hiking like Oregon, which is not allergenic?!
Thank you for your help!
