Give the child to my aunt for adoption. How can I get an account? Can I change my last name?

Notarization will do. You need to notarize that your son is her aunt's before you can apply for immigration (involving notarization of your son's birth and notarization of his aunt's marriage (divorce) in the Mainland). But this process still has to wait. When my friend went abroad with him in his twenties, he went to a notary to prove that he was the son of menstruation, but for this reason he changed his surname-after his mother and menstruation, he changed his grade. 2/kloc-you can only apply if you are under 0/year old. I don't know which country you are going to, but it is stipulated by the United States. After everything is done, he will ask his menstrual lawyer to apply for going abroad, and then the lawyer will hand it over to the immigration office for filing, which will take several years.
