Im not sure what problem you are having.
Importing images into Lightroom is not difficult and the process is not designed to be like Photoshop.
Photoshop opens images and close them.
Lightroom catalogs them. The images can remain in their current location or can be copied or moved to a new location. From there they can be edited using Camera Raw controls.
One doesnt actually "open" and image in Lightroom.
Perhaps you could clarify the problem you are experiencng
