Also make sure your kids have American Citizenship with American Passports.
Nechomah is right about the husband, It might be more difficult than you think, When you apply for residency for him make sure you apply under EU Passport and not Israeli (EU citizens have easier rules than Israeli citizens) for example EU residents dont need a visa to come to the US, Israelis do and once you get here assume your husband cannot legally work here until he gets a green card
