When my DS and DD came home (both came home at different times) I had brought everything I came home with to social security. Make sure you bring spanish and english translations. Both of my kids came home on IR-4 visas. When I applied for their ss#s I had their permanent resident cards with me as well. So, if anyone reading this post and your child(ren) came home on an IR-4 you may want to wait to get SS# until you have permanent resident card.
