Sorry, I wasn't clear. I am a naturalized citizen. My children are 10 and 12, they came on immigrant visas from the Philippines. I was told they would be citizens when they arrived, but they are being mailed green cards. I filed an I-864W. They've been here for about a week and a half. I tried reading about how they become citizens, but it looks like they have to be here for 2 years, or is that for adopted children?
