Adopted from Canada - US Citizenship as an Adult?

[maxwellmayhem]

I was born in Canada in 1978 and adopted by my parents in Utah when I was a
few months old. Neither of my birth parents were US citizens, but my
adopted parents are. My adopted mother has dual-citizenship (US &
Canada) and my adopted father is a US citizen. They did not fill out
the appropriate paperwork when I was under 18, so I do not have a
Certificate of Citizenship or any citizenship documentation. I have a
delayed birth certificate from Utah, my Canadian birth certificate,
adoption paperwork, and a Social Security number that was given to me
when I was temporarily in foster care as a teenager.

I need help to determine if I am a US citizen and how I can get a
passport. If I am NOT a US citizen, I need help figuring out what are
the next steps I need to take to legally become a citizen, seeing as
how I was adopted by US citizens and have lived here my entire life.

I was advised by the USCIS Customer Service line to make an
appointment with a local office, however, there are no appointments
for information/services at the local office. When I have previously
visited an immigration office, they weren't sure what I should do.

I have been reading and re-reading information on the USCIS page,
and it's quite unfortunate that I was not under 18 in 2001.

Any guidance would be very much appreciated.

I don't think you are a US citizen. Prior to 2001, the rules for derivative citizenship for adopted children were different than for regular children, in that the adoptive parent(s) must naturalize after the child was adopted and living in the US as a permanent resident. Your parents were already US citizens at the time you were adopted, so it didn't apply to you.
