According to Illinois Politico Playbook, there is talk that the Illinois legislature will pass a bill moving the 2022 primary from March to a later date. This is because there is so little time for new U.S. House and state legislative districts to be drawn. See here.

Moving the Illinois primary to a later date would not affect the petition deadline for new and previously unqualified parties, nor independent candidates, because the law ties the petition deadline to a number of days in advance of the general election. Specifically the independent and minor party petition deadline is 134 days before the November election.
