永久居民的未婚21歲以下孩子是F2A類型，有大概兩年排期，但是如果孩子移民前你入籍，你可以升級類型，所以現在申請沒有害處。
你是母親還是父親？如果是父親，給非婚生子女申請移民，要證明子女是確立婚生地位了，或者要證明你和孩子在21歲之前有真實父親和子女的關係。母親就不需要。看I-130 instructions，第7頁：
“D. A child born out of wedlock and you are the father: Submit evidence that you and the mother were married
while the child was under 18 years of age, or submit evidence that the child was legitimated under the law of the
child’s residence or domicile, or under the law of your residence or domicile, before the child reached 18 years of
age. If your child was not legitimated before reaching 18 years of age, you must file your petition with copies of
evidence that a bona fide parent-child relationship existed between you and the child before the child reached 21
years of age. This may include evidence that you lived with the child, supported him or her, or otherwise showed
continuing parental interest in the child’s welfare.”
