My son came to US on a K4 visa. I filed an I 130 for him when I got my green card. After my divorce, I remarried again to a US citizen and He filed an I 130 and I 485 for my son. The I 130 I filed has been approved but there is no visa number. The other petitions are still pending. Do I need to withdraw the I 130 I filed or do I wait for the outcomes of the petitions filed by my spouse? Any advice? Thanks
