Yes, sems are available. You usually have to go through a US program, i.e the school is an Israeli branch of an American program. Totally above board and legit. The schools takes a processing fee.
Two schools I know of are TI (Skokie girls’ program) and Touro. You have to check about how well the credits will tranfer though, and some schools don’t like you using their program if you have no real plan to continue once back in the states.
Is anyone in your school willing to help guide you?
And don’t forget MASA, your local Federation’s grants, etc.
