In considering control I tend to think of the two types of control, military control and loyalty. Often in the border regions, one side will have military control while the other possesses the loyalty of the region. In these mixed control regions you can take more risks with the movement of units as the region quickly passes into your control.
There really is no way to enter a hostile region without shifting into attack posture. You can minimize the consequences of entering a hostile region by selecting the avoid combat option or by timing your movement to arrive day 14 or 15. Of course if you already have some sort of force in the area you simply plot your move to join that force.
Absent the above, enter with overwhelming force so you gain military control in a single turn.
