From Yeshiva World News:
Talmidei yeshiva and avreichim wishing to travel abroad for Rosh Hashanah are required to get permission from the IDF or they will be prevented from leaving at the airport. That said, a group of Lubavitcher Chassidim wishing to head to 770 for Tishrei were informed by the Vaad Yeshivos that the induction center is not providing this service for the coming two weeks.
There are many talmidei yeshivos planning to head out of the country but they have been informed that anyone who did not secure the permit by today, Wednesday, 22 Elul, would not be able to do so in the coming two weeks. During this time period, there will be no services given at induction centers.
The letter received by the Vaad Yeshivos states the service will cease from Wednesday, 22 Elul through Tuesday, 6 Tishrei, citing all services at induction centers will stop including permits for travel abroad.
The continuation of the letter states “please bring this to the attention of talmidim, that they would expedite seeking services before Wednesday.”
