no one really knows for sure that they’re staying forever, and that’s part of making aliyah. if you are intent on returning and playing around with the government, I hear you. But if you may stay it’s not your requirement to commit forever before you make aliya.
Most people who sign up stay, some come back. I know people who made aliya hoping to work things out, but moved back due to financial worries. It’s not playing the system at all.
If you ever experienced trying to get something done in an Israeli government office, you wouldn’t have this back-bending sympathy. They have a round robin of recriminations that would make the 3 stooges proud.
