hey joe...you are basically right...that's the profile of the ATP checkride....dont forget probably an extensive up to 3 hours ORAL test before the flight...specially since you come right from another country..so the examiner may have you a little longer than usual JUST to make sure that you know the stuff.........(not because you are foreign...dont misundertand it....i am as well)
the flight part is the same multi-instrument checkride...vmc demo..single engie drills...approaches..etc....BUT it has to be done with a proficiency level according to th ATP rating....in other words....dont bust the numbers by more than "1" (whatever measure we use, feet, knots, DOTS) or you are history........( a little exagerated...but quite true if you read the PTS for ATP)
now regarding flight schools..well it's really up to how much money you want to pay.....ALLATP is a very good place with a nice reputation and a lots of schools in the country....HOWEVER you pay much more just for the name.....actually you can go to any local flight school....and do your atp there.....the breakdown will be something like: $ 300 to 500 examiner fee......$150 to 240 multiengine plane an hour.......$20 to 40 instructor an hour to get ready for the checkride (altought you DONT need 3 hours of instructtion within the 60 days...as you do in the other checkrides........i hope you dont expect to arrive in the US and schedule the examination right of the bat.....as you will find out later that you dont know much about US flying)
so consider doing at least 5 hours with an instructor.....
i wish i can help you on this one, but i'm not an MEI yet..

otherwise..i woulndt charge you for the instruction ( i like foreign people coming here and i help them)
so colorally....call ALLATP...or call "buddys flight school" (ficticious)
but after you decide where you go....i sugest start to study the ATP written prep book....(get it online) and the PTS for the ATP......
then come here...fly...pass the ride...get your temporary licence..and go buy a few beers and get a nice bad looking redneck girl....and have fun

( the good looking ones...are always taken)
anything else i can help you...just let me know
