Yes, that's a good point. Even with some form of executive due process it will never be likely that foreigners abroad have more or equal Constitutional protections than citizens on U.S. soil, and the NSA could tie back into that.
The fact that the person was in a foreign country doesn't mean that there isn't evidence available to domestic law enforcement agencies.

So, I wouldn't agree that being outside of the USA makes you safer from any consequences imposed by the US government as a result of surveillance information gathered by the NSA.
