It’s been 23 years, but my daughter got none of that. We went to the immigration office, I signed papers, they gave me the certificate, took her green card and that was it. she did get two little American flags (that we still have). She was 4 so she didn’t need a driver’s license or to register to vote, but we didn’t get a new citizen package or anything else telling me what to do. She was never invited to a ceremony (some adoptees were, but she never was). I took the certificate to the SSA office to change her status (VERY IMPORTANT TO DO). I got her a passport about 6 months later. SSA was free, everything else had a fee.
No letter from the President. I know a lot of parents delayed the Certificate of citizenship because they didn’t want that president’s signature on the certificate. Then they ‘forgot’ to get one. Oops.
