depends on how to proceed with the case. If you become a U.S. citizen in the next 2-3 years, it’s better to file a new I-130 for the child. If you remain as F2A, you can add the child as derivative beneficiary at NVC. I was in same situation, my child is born and my lawyer suggested to file a seperate I-130, which I did. With the long wait times, my suggestion would be to file a seperate I-130 once he’s born, if and only if you’re gonna be a U.S. citizen in the near future

if you are a citizen you can request a CRBA at the embassy of the country of your wife.

and I think the permanent residents can do it too. please refer information about CRBA

you do not need to do anything for the baby. he/she will be a derivative under your wife. if you become a US citizen your baby is can also apply for a US passport. long story short you don’t have to do anything for the baby.

if u are us citizen you don't need to file for baby .you need to apply for us passport for that baby then they will guide you through the process the baby will go through a medical screening to make sure your DNA 🧬 matches . but ofc you have to do the paperwork first .

The Process: Filing a Petition (I-130) As a Green Card holder father, you must sponsor your child for their own Green Card. This is a multi-step process: File Form I-130: You submit this to USCIS to prove your father-child relationship. Required Docs: Your Green Card copy, the child’s birth certificate (showing you are the father), and your marriage certificate to the mother (if applicable). Wait for "Priority Date": Your child will be in the F2A Category (Spouses and Unmarried Children of LPRs). There is usually a waitlist for this category. You can check the monthly Visa Bulletin to see how long the wait is. Consular Processing: Once a visa number is available, the case moves to the National Visa Center (NVC) and then to the U.S. Embassy in the mother's country for an interview. Travel to U.S.: Once the baby is issued an Immigrant Visa, they can travel to the U.S. to receive their Green Card. Is there any way to travel sooner? Because the child's mother does not have a Green Card, the baby does not have a "right" to enter the U.S. immediately. Here are the only other (though difficult) options: Humanitarian Parole: In extreme emergencies, you can apply for "Parole" to allow the child to enter for a temporary period. This is rarely granted for standard immigration cases. Visitor Visa (B2): You can try to apply for a tourist visa for the baby, but the Embassy often denies these if they know the child intends to stay permanently. Wait for your Citizenship: If you become a U.S. Citizen while the process is pending, the child's category changes to "Immediate Relative," which removes the waitlist and speeds up the process significantly. A Critical Note on "Legitimation" If you were not married to the mother when the baby was born, you must prove "legitimation." This means showing that you have a legal father-child relationship under the laws of the country where the child was born or where you live.
