Read it again. It never once says that those agreements are required to be recognized. It says

a nonresident of Illinois may carry a handgun in accordance with this Act if the nonresident:
(A) is 21 years of age or older;
(B) has in his or her immediate possession a valid license that authorizes the individual to carry a concealed firearm issued to him or her by another state; and
(C) is a legal resident of the United States.

And goes on to say that it "applies only to nonresident concealed weapon or concealed firearm license holders from states that honor Illinois concealed weapon or concealed firearm licenses."

There are a number of states that will only recognize a state's permit if that state recognizes them, so the reciprocal agreements are important and "the Department" is required to make them, but they are not required to be recognized. Iowa, for example, has universal recognition. Since Iowa recognizes the permits that would be issued under this law, Illinois would automatically recognize Iowa's.

Thanks for clarifying. It looks like we MO folks would also be good to go, since we also have universal recognition. It would be great to be able to carry when I visit the in-laws.
