While travelling through the Americas, the ship Einstein was on stopped at Costa Rica and El Salvador but it's unlikely he ever got off and explored those countries.
There is a rumor that Albert traveled to Albania in 1935, but there is little evidence to support this and he was already hard at work at Princeton.

Did I miss any countries? Let me know, please!
