When does the 180 day clock start for using AC21 provision to kick in for concurrent filers? Is it from the day when 140/485 was filed or from the day when 140 was approved.
In other words, at the time of 140 approval, if one has already passed 180 days, can he/she make the use of AC21 provision the very next day or he/she needs to wait for 180 more days after getting 140 approval.
