First of all, let me tell you that at an appointment at the US Embassy in Argentina, upon issuing the IV, I was informed that my son would become a US citizen as soon as he stepped onto the US.
I did not request a GC, the card arrived to the address where I was living.
Secondly, I was pregnant at that time, and all of the sudden I had serious health issues with my pregnancy (as I already had a stillbirth at 6 months-old), I left abruptly back to Argentina, where my primary care doctor and the father of my children reside.
I was alone with my 2-year-old child (who is 9 now) and pregnant.
