2NE1 is in the States?

Girl group 2NE1 is officially commencing their activities this summer, but wait, they are in the States? Recently they've traveled to the U.S, Britain, Japan and they've just left for the U.S again last weekend. 2NE1's visit to the States was made known via Park Bom's me2day as she wrote, "Where am I?" along with a photo. These words and photo alone have served as a notification for the general audience. However, since Sandara has to film for Taeyang's upcoming MV for I Need a Girl, she will leave Korea in 2~3 days time. YG Entertainment spoke up and stated, "With a comeback just ahead, 2NE1 is at the climax of preparing for their new song and practicing..." but kept their mouths shut about 2NE1's stay in the States. YGE is being secretive about this situation, but hinted that 2NE1 is either in New York or LA. With just limited information, netizens have started speculating that 2NE1 are planning to follow the footsteps of the Wonder Girls and are planning to advance overseas. It is also known that a lot of management companies in Asia and the U.S are showing their interests towards 2NE1. However, in response to these assertions, YG stated, "2NE1 isn't ready yet. For singers, content is an important factor. With the reopening of their activities, it's important for them to increase the quality of their contents by having a reasonable amount of time for preparations." So, is 2NE1 weighing the chances for a possible advancement overseas? Or are they participating in a secretive training in the States as a preparation for a comeback in Korea? As of now, all of this remains a mystery.
