First, welcome to America.
The good news that getting your ATP will count for your Flight Review (the B was dropped from the official title years ago) and IPC.
The bad news is your multi time is low. All the RJ operators are going to want 100 hours MEL. Even Cape Air flying CE-402s wants 25 MEL for their F/Os. You will have to find some way to up your MEL time to be competive.
