Pretty sure the author is a he.

I'm assuming the dating pool is already not huge. Reducing it further by trying to find another foreigner to date would just make it really hard to find a partner.

There is no mention of the "importance" for the partner to be American. The author only describes the uneasiness that stems from the suspicion when dating Americans. FYI, If you live abroad in a foreign country for years, it is not uncanny to develop relationship with 'locals', as they tend to be the majority of the people you interact with (even in a very cosmopolitan city like NYC).

I see, I have never been to NYC. Usually I as a guy meet local women depending the local male/female ratio. For example in Zurich most of the male foreigners I know invite women from their own country to live with them, or have long distance relationships.

But actually the foreigner gay scene there is quite big there, it's easy to find single gay guys at parties (I have been there with a gay friend).

Author is male i beleive. Also if he would shrink his dating pool a ton if he refused to date Americans.
