So they tour everywhere but the US right after their album comes out until probably September and then only have 9 dates in the US. Oh well.
Welcome to the life of a Linkin Park fan haha. They play one or two US dates a year (Cali and Vegas usually) when a new album comes out. They tour the world first and then on their 5th leg, they come to the US. HCT was the only time they didn't follow that plan and played the US leg 2.
