Chance Me! (American applying to top UK LLB courses)

I’m a rising sophomore and will be entering the LLB as a first year.

I know that Oxford is pretty much out of the question for me so I’m thinking of adding in KCL instead.

Do you know if there is any central location where I could ask about my chances at getting a training contract/visa. I know it’s hard to predict as we don’t know my potential course or grades, but I’m having a hard time even finding general information about international students’ chances.

Kind of a tangent, but does anyone know how foreigner’s fare doing a PGDL/Senior LLB employment wise?
