遞交485時需不需要這些關於新工作starting date等相關信息？
-Yes, but your H1 transfer receipt has indicated your legal work and USCIS will not pay attention to whether you stop working or not if the H1 is approved before Oct. 1. Also, a few weeks of illegal work does not affect anything and even more, if you visit China some day before you file I-485 and get the H1 visa to come back, this kind of record will be removed automatically.
