Junior Enlisted in the Army - Privates and Specialists - are promoted automatically based on their time in service and time in pay grade. Privates (E-1) are promoted to Private 2nd Class after completing six months of service and PV2's are normally promoted to PFC when the have 12 months' time in service and 4 months' time in grade. In general, Soldiers earn the rank of Specialist (E-4) after having served a minimum of two years and attending a specific training class.
There is an automatic promotion to E4 at 24 months time in service/6 months time in grade. 3 months time in grade with a wavier. To answer your question. The minimum TIG and TIS is 6 months as a PFC and 18 Months Time in service. So yes, you will be waiting for another 4 months at least, thats WITH the waiver. Without I believe it's something along the lines of 12 months TIG and 24 months TIS.
