FDR was also the President of the US who refused to grant asylum to Jewish refugees from Nazi Germany, if making Immigration decisions with a religious component is your interest.  

MS St. Louis.  

"The SS St. Louis sailed from Germany in May 1939 carrying 936 (mainly German) Jewish refugees. On 4 June 1939, it was also refused permission to unload on orders of President Roosevelt as the ship waited in the Caribbean Sea between Florida and Cuba. Initially, Roosevelt showed limited willingness to take in some of those on board. But the Immigration Act of 1924 made that illegal and public opinion was strongly opposed. The ship returned to Europe. 620 of the passengers were eventually accepted in continental Europe, of these only 365 survived the Holocaust."
