Hi,
I am getting ready to submit a IR-1 for my spouse who came in on a K1 five years ago and we got married she returned to Mexico. We were separated for a while, and with time have worked things out. Anyways I know for her child I did a K2 back in the day which was easy. But for this petition is there an additional cost on the IR-2 petition? Do I file at the same time?
