Hi,
I (non-American, non-Swiss, living in Switzerland) am considering making a real-estate investment in the US, which will require me to get a US ITIN number, and to submit tax return forms in the US for a few years.
Could it have any negative implications for my life in Switzerland? E.g would the Swiss banks or authorities consider me a “US person” for any matter and have any new restrictions or requirements for me?
Thanks!
