I agree with my colleagues.
(213) 394-4554 x0 Mr. Shusterman is a former INS Trial Attorney (1976-82) with over 35 years of immigration experience. His response to your question is general in nature, as not all the facts are known to him. You should retain an attorney experienced in immigration law to review all the facts in your case in order to receive advice specific to your case. Mr. Shusterman's statement above does not create an attorney/client relationship.
The short answer is yes, you can sponsor her whether you are a resident or a US citizen. BUT whether he will be able to enter the US depends on many details which you have not mentioned. Speak to an attorney
