Start with searching the AID All Israel Database. It included over one
million lines of records including many immigration files. The database is
searchable in English and Hebrew. Go to the Israel Genealogy Research
Association https://genealogy.org.il/ IGRA register for the site (it's
free) and then start using the database.
