Hmmm, I think no.
As I know, but may be I'm wrong, if you have bachelor degree in medical professions, like my wife ( physician), you need only to pass exam to get RN license. No need to study 2 years (only if you want to get nurse diploma bachelor degree, but you can work without it but for less salary) My education is - English language philologist and I also have nurse diploma, because in my university we had additional medical education (need to study 1-2 years to be passed to NR exam). But main applicant is my wife. So, I need to tell consular, that according to sec B, (iii) of 10014(not second P.P.), it's not difficult to get license and stand with medical workers of US against COVID-19. I hope it should work.
Second challenge is to get emergency appointment. But I think our embassy would be opened and I don't need to find way how to get an appointment
Tnx for your replies and opinions!
