Art wisely asked the same question on Slovak World, where Prof. Votruba provided one of his usual thorough answers. Since S-W and S-R overlap a bit but do not address the same audiences, I am repeating that answer here:

You probably have your sources, Art, on where he was taken to register what. The following is merely an answer to the question below, what were people like your grandfather seen as by the U.S. during WW II:

The U.S. recognized the emigre "Czechoslovak government in exile" (based in London) as the only representative of all of the territory and citizens of pre-WW II Czechoslovakia and sent an ambassador to that entity in early 1941 (the same person served as the U.S. ambassador to a number of other "governments in exile" in London during WW II).
A legal consequence of that was than anyone in the position of your grandfather was seen as a citizen of Czechoslovakia by Washington during that time.

No. Neutral countries did not maintain interest sections in belligerent countries on behalf of the citizens of their enemies, although even that would have been formally impossible between Bratislava and Washington during WW II.
Slovakia's President Jozef Tiso signed a declaration of war on the U.S. in December 1941. But Washington took no formal notice of the declaration, it had recognized the "Czechoslovak government in exile" much earlier (see above) and, as a result, the Unites States did not consider Slovakia to be a political entity during WW II.

Slovak World is for All things Slovak, while Slovak Roots restricts itself to genealogy. S-W is ideal for a thorough discussion of the Benes decrees, politics, history in depth, and even cheese wars.

Since he immigrated in 1905 from Presov, then the Kingdom of Hungary of the Austro-Hungarian Empire and was ethnically Slovak and never became a US citizen what would have been his stutus living in NYC. I vaugely remember someone taking him to some government building in NYC for registration but as what? Could Switzerland or some neutral power have represented the interests of former Slovaks during the war?
