@Deejee I saw people DQd on January 9th getting their IL earlier this month so I assume that was the cut off date. If we follow the same pattern as the last IL letters that were sent out on February 13th, people who were DQd in December got their interview appointment at the beginning of the month in March, and people DQd earlier than us in January got their interview appointments on late March. Following this, I guess we will get out interview appointment at the beginning of April.
Or maybe that's just me trying to be positive after all this exhausting process..!!
