Can I transfer as a Junior?

I go to a small private liberal arts college in eastern Pennsylvania and I’m currently a sophomore economics student about to finish his 2nd year. I want to be an economist of some sort (not exactly sure what type specifically) but I’m pretty positive I will need the best degree possible to do what I want to do. Their is a really good college, I think it’s 36 best in the nation, right next to my school and I would really like to transfer over. I’m working on getting my grades up and meeting the credentials but will they let me transfer? what are the complexities? do you know anyone who transferred as a junior? thanks for reading.
