Hello suzanne4,
First of all, thank you so much for helping all of us out and answering our questions. I do have couple more:
I graduated from US university with BSN degree last May and just got my RN license in NY.

Currently I am on a A2 visa and live in NY. I do understand that my best choice will be applying for a green card (once I will find an employer). Now can you please clarify it for me:
Do I need to apply for a Visa Screen
and credential verification in NY or just the visa screen?
- should I take any English proficiency tests?
- should I be looking for a hospital before I get that visa screen certificate or only once I got it?
- Do you have any idea how long is the process from the minute you get your visa screen done till you get you green card?
-what are my options for working in the meantime?
- are you familiar with any hospitals in NY area that will hire nurses in my situation?
Thank you in advance,
