You or one of your siblings may be able to petition for your mother to receive an immigrant visa if you are United States citizens at least 21 years of age. The process your mother would need to follow would depend upon how she entered the country. Did she last enter at a border crossing? If not, she may qualify for parole in place given your brother is in the military. I would encourage you to speak to an attorney.
