I would suggest you check out the International forum found by clicking the Local tab near the top of the page especially the thread/sticky titled
Primer to working in the US You are aware that CA will not issue you with a license until you get to the US and can prove there with a valid work visa, but they will isue you with a letter stating you meet requiements and if not in the US within 3 years you will have to re apply although will not have to repeat NCLEX. There is also retrogression and all countries currently affected.
I really suggest having a good read in the International forum I am sure you will find all your answers
