wow, I think we are being a little harsh on him.
I never planned to have a baby here, especially not for the purpose of seeking residency, but it happened and if our plans work out and we decide to live here it is probably are easiest chance to get citizenship.
Right now we are small family of three different nationalities (venezuelan, american, argentina) I find it necessary and important that we all have residency from the same country or citizenship of the same country just for the sake of being a family and sticking together. That's why these laws were made, so that families don't get torn apart.
I really doubt if this guy isn't even sure about the residency process that he would have a baby only for that purpose.
