As your husband even though being UScitizen, as at present working in India, you can file divorce case in India and get it served the court notice without any hassel and the role of US Govt. does not arise. You can file inteerim maintenance application for maintenance during the pendency of divorce case and once divorce case is decreed in your favour, you can move an application for permanent maintenance. If he does not come to terms by mutual discussion for compensation, then you can follow the above procedure. If you are also not working, then you can move S.125 cr.p.c. maintenance petition along with interim maintenance application and this case is permanent nature. As he is working in India and his employer is an Indian company, you will be having no problem.
