Credited. The schools will know best.
LSAC data shows that 4% of the students
in Rutgers-Newark's part-time program
are foreign nationals. So it's certainly
possible.
You still need to figure out (a) what kind
of visa you need, and (b) whether the schools
you are applying to are ok with it.
If you can't get work authorization, then
some schools may want to know why you
are applying part-time, since you won't
be working.
Also, I *believe* that you are not supposed
to indicate an intention to stay in the US
if you are on a temporary visa such as a
student visa. I would think that going to
a US law school indicates an intention to
stay in the US, but that's just me.
You need an expert.
Talk to (1) the admissions office and/or
(2) the international student office at
different schools.
I would suggest Rutgers-Newark or Seton Hall
as the New Jersey schools get the most
international students.
