I got my green card last July 21 and I am ready to petition my 20 year old son. I was H1B before married USC last Oct. got my greencard last month. I have 3 kids, 20, 10 and 9 years old. My 10 and 9 year old kids was being petitioned by my husband as step son and step daughter, but since my eldest is already 20 yrs old he wasn't able to petition him as his step son. So I will be the one who will petition him. Somebody help me please how will I start my petition to my son I don't have money to go to lawyer. And I don't my son to age out. So please give me advice.
