Isn't it above 1mln? (US citizen working in London told me he has to make the tax return, but he is not tax for anything below 1 000 000 $)

  No, it is $100k. That also only applies to income tax, not social security.

  It's $100,000 not 1m. Many countries have a tax treaty with the US so that you're not double-taxed, but instead pay the greater of the local rate or US rate.
