1) Apply for MASA. Its funded by the Israeli government, and I believe they give up to $4000
2) Apply for TAP/ PELL from the US government. You can apply that money toward your seminary tuition by going through colleges with Israel programs, such as Touro, Stern and TI.
3) You can apply for any college scholarship and apply it toward seminary through those same Israel programs. Deadlines are coming up very soon for most college scholarships, so you may want to get working on that. You can search online- there are websites that have listings of scholarships that you can apply for.
4) You can ask your seminary for a scholarship.
