I knew a couple guys who had very slight russian accents despite growing up entirely/mostly in the US. One guy was born and raised in the US, but went to a Russian speaking primary school and while he didn't have a thick accent, he didn't speak like other people from our area.
The second guy was literally born in moscow, but immigrated young but also spoke a loott of Russian growing up, he had a thicker accent.
I knew a kid (middle school age) who had a Russian accent, though I can't recall which country he was born in. He did live in a neighborhood of Russian immigrants though. I also knew someone in high school who was born in California, but spoke with an obvious Mexican accent.
