Congratulations on your new baby! Please, don’t do that once you spouse bring the new baby and you his papers like birth certificate, passport etc... you can update your application. Don’t assume on something not verifiable.Thanks so much. I will do that.
One more question. My spouse and I have a child and we're expecting another soon. Can I put my dependents as 2 and update later for additional dependent after her delivery or just put 3?
