I came to the US by marriage to USC with I-130 petition and did not list my child as they were not migrating with me at that moment. I am now a green card holder and have been so for the last 6 years. I have talked to a few people and they told me that I can now not petition for my child because I did not list them on the I-130 form. Now I am worried and was hoping I could get some other advice from people on this forum. Thanks for any info.
