For Kangana Ranaut, every trip to the US has been enriching. Her upcoming trip , which starts next week, will be more than a month long. The actress is set to begin her new film ‘Simran’, the prep for which is already under way. To be shot across Las Vegas, Nevada and San Francisco, the movie will also see Kangana essaying an NRI bank robber.During her stay in the US, she also plans to squeeze out some time from her packed schedule to enroll for another short course. A couple of years ago, the actress did a two-month course in script-writing from New York Film Academy. Whether she will have enough time to pack in so much on this trip, remains to be seen.
