Hi Deza,
I sat the part 135 ATP written here in UK and went to a school in OK USA to do a checkride for an ATP Multi engine land, I personally did a few hours with an instructor to make sure I was OFAY with it all though. The examiner will issue you with a temporary airman cert at the end of test and you will get your ATP proper in the post in due course.
Good luck, I really enjoyed my time over there.
