It seems like you're fixated on getting into the U.S.
I've seen a lot of people in this state of mind, and it seems to me that wanting something desperately makes it hard to actually get it (it puts you in the wrong state of mind).
Focus on building a great product and don't think about being acquired. Make something people want, get users to love your product. Find ways to monetize the wealth you created.
It seems like what you're really asking is "I want to get into the U.S., can I do that by making a website and hoping to get acquired?".
