Hi Peter, I am a naturalized US citizen (via employment sponsored H1B to Green Card route). Prior to obtaining my citizenship I held an F1 visa to complete my PhD, and may have overstayed in the US at the end of my studies (I am not sure, this was 15+ years ago). This was never raised as an issue when I applied for my H1B, Green Card or citizenship, but is it something that could become an issue for me now if I travel as a US citizen and attempt to return to the US? Is there anything I can do proactively to address this if it is likely to be a problem? Thank you.
