You shouldn't even need a check flight for the licence issue. It is issued at the office based on viewing your licence etc. As for renting a plane different story obviously. I think you will need an FAA medical to be able to exercise the privileges of the licence. It's been a while since I converted mine and also got a CPL at the same time (had to do flight test for that) so could be wrong on the finer details. Have fun over there!
