Congrats! As far as I know, you can only work privately, unless a nursing home or something is willing to overlook your status. You can try to get sponsored through employment, but visas for RNs are currently backlogged, and the wait can be as long as 5 years. You will also have to prove that there is no other legal resident available to do the job (hard to prove in current economy), and you also don't get authorization to work while you wait for visa.

Visas for masters-level nurses are current (meaning it'll get processed right away; EB-2 category), so if you happen to return to school to get your masters, you can try to get sponsored that way. Your only requirement is to prove no legal resident available to do job, in which case, there will be less competition. Same goes for dreamers who are pursuing physical therapy/occupational therapy I believe.

In any case, congrats again. At least now, no matter what happens, you can go anywhere and have a source of employment.

And if you decide to work privately, get malpractice insurance, so that you're covered. I got mine through NSO by filing out paper form.

Good luck with everything!
