You can have your mother come as a nanny if you want to go that way. It would mean she would be hired by your husband and be the sponsor for her to work here. I have filipina workers that have done this in the past year. It takes time for the paperwork to go through but he would have to allow it. If he and she gets along with no problems then go for it but if they do not it could cause alot more problems then good. Even if you want to work.
