In other words, gun rules from your home state would follow you wherever you travel. The problem is, Illinois is the only state that does not allow concealed carry.
That means if it becomes law, a person from Missouri could come to Illinois, carry a concealed gun and not get in trouble. If you are an Illinois resident though, you could not carry a concealed weapon.
The state says it would be too hard to police and would be unsafe. Gun advocates say it is a basic right and is important for self defense.
Illinois is not the only state fighting this bill. Leaders from nine other states including New York and California are also saying no.
