I got a call this morning from the consulate that my kids paperwork has been processed and they're ready to proceed with the application to renounce citizenship.
Only a clerk at the Israeli consulate could ask the following question: "Would you like to come in here again or send things by email?"

In any event, since both myself and DW are Israeli citizens, they asked that she too complete an application for renouncement (even though her details are mentioned on my application, but they explained that it is informational only, and every adult needs their own application, and since she's a parent, she needs to list/include all the children too).
While AFAIK the fee is ILS 345, they probably update the USD fee periodically, rather than charge the ILS fee, so the recent USD strength that would make that less than $100 per applicant doesn't seem to help. They want to charge $114 each (including each of the children).
I emailed the documentation they requested and am waiting for a call back to take my CC information to charge and get the ball rolling (at least it will help with the SUB for a card).
