On December 14th we visited the Department of Defense. Maybe it wasn't really the DoD, it was US Citizenship and Immigration Services, but DoD is more fun to say! Jack received his Certificate of Citizenship during this visit. I was hoping for some sort of ceremony or something, but we got none. This is also the very last document related to his adoption to be completed. It took us 2 years and 9 months start to finish for all the paperwork (we filed the very first form, the I-600A, in March 2004).
It's nice to be all done with the paperwork, there is an incredible amount for adoption! (I think you have to fill out equal number of pounds of paperwork to your child's weight.) And we are done with all the fees to the USCIS (for Jack's adoption anyway), and done waiting to find out if something was written incorrectly and for confirmation of receipt.
So Jack is an offical US citizen in his American name. He will be able to vote and we can get him a US passport. And he now has proof of his citizenship status in the Sweet Land of Liberty. Congratulations, Jack!
