Quite possibly your Grandfather was taken to file his Alien Registration Papers...these records can be obtained from The US Archives.

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?
