Hello All, 

I was told by my grandfather that he tried to sponsor his sister and her family to come to the US from Romania/Hungary before WWII.  Is there anyway to find this record?  What agency would I contact?

Janis,

I would start with HIAS. https://www.hias.org/records-search-requests

AJHS has a HIAS client database, but it is a later time frame than you require.
