Many Hosptitals do not want to take the burden of dealing with immigation and thats the main reason they prefer bringing Intl. nurse through agencies. One of the reasons, why hospitals stay away from it is, if they do, they have to disclose their (financial) details to an attorney.
But since you have already found a hospital to 'officially' sponsor you, you are half done! I used 'Officially' because they may be your 'sponsor' in papers but you may have to bear all the expenses, find a good attorney (with whom even the hospital is OK) and have to do all the paperwork. I would suggest you to talk to an experienced attorney, who has some experince in THIS field.
Yes, you need to have EAD on your hand to start working. Once you file your petition, it would take around 60 days to get your EAD and this depends on your service center. TX,VT are much faster while CA is pretty slow (90 days). As a matter of fact, you need EAD and SSN too. Once you have EAD, SSN is 'ussualy' a matter of one week.
If your hospital wants you, then they must have to wait because there is no short cut there. Also, for hospitals, it is illegal to employ someone without proper work authorization from USCIS. Since RN shortage is rising steaply, I don't think they will act crazy provided you can explain them the normal procedure and the time it 'ussualy' takes.
Also, as you have stated clearly, you do not need
your Visa screen to apply for I140/I485/EAD. VisaScreen is only required when they look at (start adjudication process) your case. But, it may be a good idea to start the process RIGHT NOW, because you are dealing with a monopoly (CGFNS) there.
Quote from Enigma
I would really appreciate if somebody could help me clarify the process of getting the EAD.
I am a RN (just got my licence) on the legal status in the USA which, however, doesn't allow me to work. I have found an employer who is willing to sponsor me, but has never done this before, and doesn't have any idea how to do it. My future employer wants me to start working ASAP, and I really need to know what is involved in getting the EAD, and how much time I have to wait before beginning to work. I am afraid of losing the job if it takes too long. It is my understanding that I can't work until I have the EAD in my on hand.
Please, share you experience how it really work from the point when you have found your employer. You had to wait for the EAD. Right? And your employer agreed to wait with you?
I am not talking here about other documentation to get the Green Card because from the moment when I can legally work, time wouldn't be a problem for me. However, I would be grateful if you can briefly mention about my next steps, and, especially, about obstacles I have to anticipate. The most common obstacle I have encountered since I started my jobhunting is that there are only few companies that want to sponsor international nurses. I am greatly frustrated, and that is why I consent to work for the the company that doesn't know anything about it, but just is willing to help so far.
I am thanking in anticipation of your reply. I wish you all the best success.
