My suggestion is to go with your hospital policy. We do not accept volunteers who cannot produce a SS# as this is what our HR does for employment.
We can onboard without a social if the have a itin number. The itin number allows them to work or volunteer.
That is a great question and have not experienced that, however I must have the volunteer's SSN for the background check only, otherwise, I am not sure I would need the SSN.
I have a Doctor who's mom is here from Venezuela and has applied for permanent residency here. She to is a Doctor and has all of her immigration information. Can we legally on board her without a background check if she has all other legal documents such as drivers license, birth certificate etc. Please advise.
