EB4 Religious Worker Green Card

[rsoltani]

A religious non-profit organization wants to hire a religious worker and get a Green Card for him under the EB4 category. USCIS website says he must “have been working, either abroad or in lawful immigration status in the United States, continuously for at least 2 years immediately before the filing of a petition”. Also on their website, “If the religious worker received no salary but supported him or herself and any dependents, provide verifiable documents” shows that the position might be without a salary.

Our case, has worked in the home country 5 years, and then he came to US and stayed here on F-2 visa status. During the stay in US, he worked for our non-profit religious organization as a "Volunteer" with no compensation.
Does this Volunteer work count toward the two year continuously working that I mentioned above?
Should the petitioner in the US organization, be a green card holder or US citizen?

Thanks,

The officer of the Attesting Religious Organization signing Form I-360 need not be citizen or permanent resident of the United States.

The alien will have to provide evidence as to how he/she supported him/herself for those two years. "This may include, but is not limited to, audited financial statements, financial institution records, brokerage account statements, trust documents signed by an attorney, or other verifiable evidence"
