Joining the US system while coming from a French university

Thank you for your answer !
I’m currently a first-year preparing a bachelor’s degree which roughly consists in the study of Math, Economics and Computer Science (the literal translation for my French diploma is : “Mathematics and Computer Science Applied to Social Sciences”). My grades are actually pretty good (the equivalent of A’s in most subjects) and I got a mention “Bien” for my Bac (15,4/20). I took both the TOEFL and the SAT last year : I scored a 104 on the TOEFL and a 1300 on the SAT (which I believe is just average).
I don’t enjoy being in the French system as I am looking for more (I realize that it sounds cheesy but I really feel this way). For instance, I would love to get involved on campus but there aren’t much opportunities here and the campus (which is a basically a 23 floor building) isn’t quite one.It is almost constantly overcast in Paris, the weather is gloomy and the city is just enormous, which can be overwhelming. Of course, Paris is really mesmerizing and is amongst the best cities in world. Nevertheless, it’s just not for me. I’ve always dreamed of joining an American university but unfortunately, I got rejected by all the US colleges that I applied to last year. I was wondering if I could have another shot as a transfer student to join a good-ranked university, anywhere in the world, in the US ideally.
