498A 11 years after marriage and 1 and half year separation

Dear Sir/Madam, I got married in 2008 and have two kids (10 and 6 years old). All through the matrimonial we lived in USA. My both kids are US citizens and I am green card holder. My wife abandoned us a year and half a ago on the ground that she doesn’t want to take care of my son, who has autism. She is in India for the past one and half year. As a single father I am taking care of my kids. My son is improving with intense therapy and training. He need this therapy for another 3 to 4 years. My family and relatives tried in many ways to talk to my wife and her family but she and her family did not cooperate. She recently filed a police complaint saying that I took away the kids from her and she also included 3 of my family members name in the case saying that they have harassed her for dowry. She never lived with my family in Indian except during our visit. The police inspector called me and asked me to come to India ASAP, if not she will file FIR against me and my family members. I am not sure in what section the case was filed (assume 498A). My question is one can file case under 498A 11 years after marriage and nearly 2 years after separation? What is the lawyer’s advice? How to deal with this matter without going to India. Kindly advice me. Thanking you in advance
